i dont really understand... it says to use vertical angle theorem
Answer:
The virtical angle theorem is that virtical angles are congruent, or equal. A vertical angle is like the angles in an X. The opposite angles are congruent, like in the picture, it is the unknown angle and the angle touching it.
Triangle ABC has coordinates A(0, 6), B(3, 0), and C(4, 3). Triangle ABC is reflected across the x-axis. What are the Coordinates of C
Answer:
C= (4, -3)
Step-by-step explanation:
If all of the points are reflected across the x-axis, then A= (0, -6) and B would stay the same since one of its coordinates is already on the x-axis.

Answer:
x = 34.85
Step-by-step explanation:
Apply trigonometric ratio formula to find x
Reference angle = x
Side opposite to x = 4
Hypotenuse = 7
Therefore,
Sin x = opp/hyp = 4/7
x = sin-¹(4/7)
x = 34.85° (nearest hundredth)

On which triangle can the law of cosines be applied once to find an unknown angle measure? Law of cosines: a2 = b2 + c2 – 2bccos(A) Triangle X W Y is shown. Angle X Y W is a right angle. The length of hypotenuse W X is y, the length of X Y is a, and the length of W Y is 9. Triangle W X Y is shown. Sides W X and X Y are congruent. The length of W Y is 7. Triangle W X Y is shown. Angle X Y W is 76 degrees. The length of X Y is 5, the length of W Y is 10, and the length of W X is y. Triangle W X Y is shown. The length of W X is 10, the length of X Y is 8, and the length of W Y is 16.
Answer:
C) Angle X Y W is 76 degrees. The length of X Y is 5, the length of W Y is 10, and the length of W X is y.
Step-by-step explanation:
On which triangle can the law of cosines be applied once to find an unknown angle measure?
The Law of cosines is given as:
a² = b² + c² - 2bccos(A)
From the options given above, the correct option is Option C
C) Angle X Y W is 76 degrees. The length of X Y is 5, the length of W Y is 10, and the length of W X is y.
This is because:
Law of Cosines helps us to find an unknown side of a triangle when we are given 2 known sides and 1 angle.
In the above question, we are given angle 76 degree, and the length of two sides: The length of X Y is 5, the length of W Y is 10
The unknown side is the length of W X which is represented as y.
Hence, Option C is the correct option.

MIguel is making a trail mix. He Uses five and one third ounces of nuts and two and tree fourths ounces of raisins Which of these is a reasonable estimate for how much more nuts Miguel uses than raisins?
(Keep as a fraction and don’t change to decimal please)
Answer:
[tex]\frac{31}{12}[/tex] more nuts would be used by Miguel then raisins
Step-by-step explanation:
The computation is shown below:
Nuts used [tex]= 5 \frac{1}{3} = \frac{16}{3}[/tex]
Raisins used [tex]= 2 \frac{3}{4} = \frac{11}{4}[/tex]
Now the difference between them is
[tex]= \frac{16}{3} - \frac{11}{4}\\\\= \frac{64 - 33}{12} \\\\= \frac{31}{12}[/tex]
Hence, [tex]\frac{31}{12}[/tex] more nuts would be used by Miguel then raisins
can someone help me solve these two problems? i need to find what x is.
Answer:
1. x=2
2. x= 0.33
Step-by-step explanation:
1.So to start off you have a coefficient for 2 so you have to find what 2 to the power of 2 is =4 so then you have your new problem 4x+5=13 next you need to get 4x by itself so
-5 -5
then you have 4x=8. you divide by 4 on both sides
4. 4
so then you get x=2
2.So same here find what 3 to the power of 2 is =9
New equation 4x-1=9x+4x-4. Then combine like terms on the right you cant do it on the left because that is a separate part and those dont merge like terms so
9x+4x = 13x
new equation. 4x-1=13x-4
next subtract 4x on both sides
13x-4x=9x
new equation. -1=9x-4
next add 4 to both sides
-1+4= 3
new equation. 3=9x
so then divide 9 on both sides
3÷9= 0.33
x= 0.33
Hope this made sense and helps

In a survey of 1.400 people who owned a certain type of car, 980 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?
Answer:
Percent of people satisfied with the car = 70%
Step-by-step explanation:
Given:
Total number of people survey = 1,400
Number of people satisfied with the car = 980
Find:
Percent of people satisfied with the car
Computation:
Percent of people satisfied with the car = [Number of people satisfied with the car / Total number of people survey]100
Percent of people satisfied with the car = [980 / 1400]100
Percent of people satisfied with the car = 70%

In ΔFGH, f = 60 cm, g = 10 cm and h=62 cm. Find the measure of ∠F to the nearest degree.
Answer:
74
Step-by-step explanation:
The measure of ∠F of the triangle FGH, where all the sides are known is 74 degrees to the nearest degree.
What is the law of cosine?When the three sides of a triangle is known, then to find any angle, the law of cosine is used.
It can be given as,
[tex]c^2=a^2+b^2-2ab\cos C\\a^2=c^2+b^2-2ab\cos A\\b^2=a^2+c^2-2ab\cos B[/tex]
Here, a,b and c are the sides of the triangle and A,B and C are the angles of the triangle.
In the triangle FGH the measure of the line segment f is 60 centimeter, the measure of the line segment g is 10 cm and the measure of the line segment h is 62 centimeters.
The measure of the angle ∠F has to be find out. To find the value of angle F where side f is 60 cm. Thus, put the values of the all the sides in the above formula as,
[tex]60^2=10^2+62^2-2(10)(62)\cos (F)\\3600=100+3844-1240\cos (F)\\ F=\cos^{-1}(0.27742)\\F\cong74^o[/tex]
Hence, the measure of ∠F of the triangle FGH, where all the sides are known is 74 degrees to the nearest degree.

Maggie wants to buy a new energyefficient refrigerator. Her old refrigerator uses about 1200 kWh per year,while the new one would use about 400 kWh per year. Approximately how much money would Maggie saveper year if she buys the new refrigerator?
Answer:
800 Kwh
Step-by-step explanation:
To solve this problem, we need to find the difference in energy saved and then multiply by the cost of 1kWh of electricity
How much did Maggie save?Let's first of all calculate the the difference in energy saved
Data;
old refrigerator = 1200kWhnew refrigerator = 400kWh[tex]1200 - 400 = 800kWh[/tex]
Maggie would've saved 800kWh in one year.
But since we were not given a standard cost of electricity, we would assume that 1kWh will cost $1.
So, to determine how much she must've saved, we simply multiply $1 by 800kWh
[tex]1 * 800 = $800[/tex]
Using our assumptions, she would've saved $800 in one year.

Find the surface
area of this figure.
2 in.
8 in.
[?] square inches
8 in.
5 in.
12 in.
10 in.
Answer:
528
Step-by-step explanation:
Surface area of bottom block + Surface area of top block - 2(Shared surface area)
Bottom block: 2(10*12) + 2(5*12) + 2(5*10) = 240 + 120 + 100 = 460 square inches
Top block: 2(2*2) + 4(2*8) = 8 + 64 = 72 square inches
Shared surface area = 2*2 = 4 square inches
Plugging into our formula:
460 + 72 - 4 = 528 square inches
The measures of the angles of a triangle are shown in the figure below. Solve for x.
Answer: 27°
Step-by-step explanation: Here, we're asked to find the missing angle measure in the triangle shown which is represented by the variable x.
To find the value of x, remember that the sum of the
measures of the angles in a triangle is 180°
So we can setup the equation 63 + 90 + x = 180.
Remember that a box indicates a 90° angle.
Now to solve for x, let's first simplify on the left side of the equation.
63 + 90 is 153 so we have 153 + x = 180.
Now to get x by itself, we subtract 153 from both sides of the equation.
On the left side of the equation, 153 - 153 cancels out and we have x
and on the right side of the equation, 180 - 153 is 27.
This means that the missing angle in the triangle is 27°.

The table shows the linear relationship between x, the altitude in feet, and y, the boiling point of water in degrees Fahrenheit. What are the slope and y- intercept of the line that models this situation?
A. Slope=- 0.0018, y-intercept = 212
B. Slope= 0.0018, y-intercept =-212
C. Slope =212, y- intercept= 0.0018
D. Slope=-212, y-intercept = 0.0018
Answer:B
Step-by-step explanation
The slope of the linear relation is -0.0018 and the y-intercept will be 212. The correct option is B.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data in the table is,
Altitude(x) Boiling point (y)
0 212.0
500 211.1
The slope will be calculated as,
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Slope = ( 211.1 - 212 ) / (500 - 0 )
Slope = -0.0018
The y-intercept will be calculated as,
y = mx + c
212 = 0 + c
c = 212
Therefore, the slope of the linear relation is -0.0018 and the y-intercept will be 212. The correct option is B.
