Find the value of x. I don’t know how to do this. Please help me

Answer:

A)4

Step-by-step explanation:

degree measure of the 4 angles of a trapezoid is 360

so

since we have only 2 angles, 360/2

180=125+(14x-1)

180-125=125+(14x-1)-125

55=14x-1

55+1=14x-1+1

56=14x

4=x or x=4

hope this helps!

Answer:

x = 4

Step-by-step explanation:

The interior angles of a parallelogram always add up to 360 degrees.

We already know that one of the angles is 125 degrees, so we can subtract 125 from 360, leaving us with 235.

The angle right across from the 125 angle is congruent to it and so now we can subtract another 125 from 235, leaving us with 110 degrees.

There are 2 angles left, they are both the same measurement, so we can divide 110 by 2, leaving us with 55.

This means that 14x - 1 = 55

Time to find x

First, we are going to add 1 to both sides in order to cancel it out.

14x - 1 + 1 = 55 + 1

14x = 56

Now, we are going to divide both sides by 14 in order to cancel it out.

14/14 x = 56/14

x = 4

Answer:

$2.498

Step-by-step explanation:

On Thursday, it would be -7°

I hope this helped♡

The integer showing temperature on Thursday is -7° C

An integer is a number with no decimal or fractional part, and it includes negative and positive numbers, including zero.

Given that, On Wednesday, the temperature was 27° above zero. On Thursday, it was 7° below zero.

Since, below zero, it starts negative numbers,

And, the temperature on Thursday was 7° below zero.

Therefore, the temperature on Thursday was -7° C

Hence, the integer showing temperature on Thursday is -7° C

Answer:

0

Step-by-step explanation:

When a number is not included or used, it can be considered 0.

This makes sense, because if it had a actualy value, it would effect the polynomial, and change the answer.

The only time it would  not effect the polynomial is when it 0.

Hope this makes sense :D

Answer:

1. Convex 15-gon, Convex 18-gon, Convex 45-gon

2. Increases

3. Decreases

4. Increases

5. Stays the same

Step-by-step explanation:

The formula for finding the measure of an interior angle, θ, of a polygon with 'n' sides is given as follows;

[tex]\theta = \dfrac{(n - 2) \times 180}{n}[/tex]

1. Polygons that have interior angles with whole numbers are factors of 180

The factors of 180 are 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, and 180

Therefore, from the options, the polygon that have whole number interior angles are;

15, 18, and 45

Which gives;

Convex 15-gon

θ₁₅ = (15 - 2) × 180°/15 = 156°

Convex 18-gon

θ₁₈ = (18 - 2) × 180°/18 = 160°

Convex 45-gon

θ₄₅ = (45 - 2) × 180°/45 = 172°

2. From the equation of the interior angles of a polygon, [tex]\theta = \dfrac{(n - 2) \times 180}{n}[/tex], we have;

As n increases, (n - 2)/n increases towards 1

Therefore, as the number of sides 'n' of a polygon increases, the interior angle of the polygon increases

3. Given that the sum of the interior and exterior angles of a polygon is 180°, as the interior angles increases as the number of sides increases, the exterior angle decreases

4. The total sum of the angles increases as the number of sides of the polygon increases and decreases as the number of sides of the polygon decreases

5. The sum of the exterior angles of a polygon is given as follows

[tex]n \times (180^{\circ} - \theta) = n \times \left(180^{\circ} - \dfrac{(n - 2) \times 180^{\circ}}{n} \right) = n\cdot 180^{\circ} - n\cdot 180^{\circ} + 360^{\circ}[/tex]

[tex]n \times (180^{\circ} - \theta) = 360^{\circ}[/tex]

Therefore, total sum of the exterior angles of a regular polygon is always (remains the same) 360°.

S∪B = {a,b,e,a,d,f,g}

Step-by-step explanation:

According to the Question,

Given, S and T are subsets of a universal set U ( U = {a, b, c, d, e, f, g, h, i} )

And, S = {a, b, e} , T = {a, d, f, g}

Thus, S∪B(S union B) = n(S) + n(T)

S∪B =  {a,b,e,d,f,g}     (There It contains all the elements present in S & B).

Step-by-step explanation:

Answer:

y= 6x -8

Step-by-step explanation:

Slope-intercept form:

y= mx +c, where m is the gradient and c is the y-intercept.

[tex]\boxed{gradient = \frac{y1 - y2}{x1- x2} }[/tex]

Gradient

[tex] = \frac{4 - ( - 2)}{2 - 1} [/tex]

= 6

y= 6x +c

To find the value of c, substitute the equation with a pair of coordinates.

When x= 1, y= -2,

-2= 6(1) +c

c= -2 -6 (-6 on both sides)

c= -8

Thus, the equation of the line is y= 6x -8.

Answer:

Rule: multiply by two

100 = 200

n = 2n

Step-by-step explanation:

First pay attention to the information given to you. 1 goes to 2, 2 to 4, 3 to 6, and 4 to 8. You need to find the rule, or how exactly the input goes into the output. Let's start with 1 x 2 = 2. That would fit for the first one. So we will try that for the next one. 2 x 2 = 4. The rule of multiplying by two works for the second one too. Now we do the third. 3 x 2 = 6. Works again. Next, 4 x 2 = 8. So the rule of multiplying by 2 works for all of the given information.

Now that we have the rule, we can use it to find the missing information. 100 x 2 = 200. So that's your first answer. The second one is a little more tricky if you think about it too hard. The simple answer is 2n. Because n is only a variable and not a real number, it can't be completely multiplied like the rest. It becomes 2n or, 2 times n.

Answer:

There are 680 buttons altogether

Step-by-step explanation:

Here, we want to get the total number of buttons

From the question, the ratio of number of red to white buttons is 4:7

mathematically, this mean;

r:w = 4:7 = ?/280

thus;

4/7 = ?/280

7 * ? = 280 * 4

? = (280 * 4)/7

? = 40 * 4 = 160

From here, we can see that the number of white buttons is 160

from the second part of the question,

b:r = 3:2 = ?:160

3/2 = ?/160

2 * ? = 160 * 3

? = 480/2

? = 240

Thus, we have the sum total of the number of buttons as;

240 + 280 + 160 = 680

Answer:

answer is option C

3+7=10

7-3=4

C.

Step-by-step explanation:

x + y = 10

x - y = 4

x = 4 + y

Okay, so now we substitute our third equation into equation 1. Then equation one becomes..

4 + y + y = 10

4 + 2y = 10 ┌(・。・)┘♪

Mk now we subtract 4 from both sides ofc.

2y = 10 - 4

2y = 6

Now divide by 2

y = 3

And now the last one-

substituting y = 3 into equation 3 to find the value of x!

(. ❛ ᴗ ❛.)

x = 4 + y, x = 4 + 3, x = 7

So, that's how I got this answer! (◕ᴗ◕✿)

Answer: 124º

Step-by-step explanation: Since RQO forms an isoceles triangle (this is because diagonals bisect each other, making diagonals congruent which forms the isoceles triangle), <QRO and <RQO are congruent, so <RQO is also 62º. This would mean that <QOR is 56º (all angles in a triangle have a sum of 180º). Since <QOR and <SOR form a linear pair, they are supplementary, meaning that they have a sum of 180º. 180 - 56 - 124º, so the size of the obtuse angle between the diagonals is 124º.
