Answer:

e = 126

Step-by-step explanation:

Both triangles are isosceles triangles. Therefore in the smaller triangle, there are two angles that are equal to 42 degrees (the other one is next to e)

42 + 42 = 84

there are 180 degrees in a triangle

180 - 84 = 96

So the last angle in the triangle (The little one) is equal to 96 degrees.

The rule for cyclic quadrilaterals is that the two opposite angles equal 180. So the angle opposite 96 degrees will be equal to:

180 - 96 = 84

As the larger triangle is also an isosceles (as mentioned above), two angles will be equal to each other. The two angles that are equal are at the bottom left. As one of them is equal to 84, the other is also equal to 84. This means the last angle (the one at the top) is equal to:

180 - (84 + 84) =

180 - 168 = 12

Angles on a straight line always equal 180 degrees. So 'e' is equal to 180 minus the other two triangle angles on the line they all share.

180 - (12 + 42) =

180 - 54 = 126

Therefore e = 126

Answer:

Step-by-step explanation:

4x + y = x + 3y

4x - x = 3y - y

3x = 2y

if x = 6 then

3*6 = 2y

18 = 2y

y = 9

Answer:

[tex]m\angle MNI = 135^{\circ}[/tex]

Step by step explanation:

[tex]\text{The exterior angle of a triangle = sum of two opposite interior angles.}[/tex]

[tex]~~~~~~\angle MNI = \angle LMN + \angle MLN\\\\\implies 19x+2=(15x-12)+6x\\\\\implies 19x +2 = 21x-12\\\\\implies 21x -19x = 12+2\\\\\implies 2x = 14\\\\\implies x=\dfrac {14}2\\\\\implies x = 7\\\\\text{So,}~ m\angle MNI = 19(7)+2=135^{\circ}[/tex]

Answer:

Let [tex]\pi[/tex] represent 3.14
SA = 2[tex]\pi[/tex]r^2 + 2[tex]\pi[/tex]rh
SA = 2[tex]\pi[/tex](5)^2 + 2[tex]\pi[/tex](5)(12)
SA = 2[tex]\pi[/tex](25) + 2[tex]\pi[/tex](60)
SA = 50[tex]\pi[/tex] + 120[tex]\pi[/tex]
SA = 50(3.14) + 120(3.14)
SA = 157 + 376.8
SA = 533.8inch^2

Therefore the surface area of the cylinder is 533.8 square inches.

Answer: Let  represent 3.14SA = 2r^2 + 2rhSA = 2(5)^2 + 2(5)(12)SA = 2(25) + 2(60)SA = 50 + 120SA = 50(3.14) + 120(3.14)SA = 157 + 376.8SA = 533.8inch^2

The greatest number of sales kits that Marco can make should be 6, with each kit having 1 tile sample and 2 carpet samples.

Answer:

A. 12 square feet

Step-by-step explanation:

So it's easier to find the area when you split the shape into 2 parts, and they already did that for you. So basically you find the area of both triangles and add them together. The formula for a triangle is base x height divided by 2. You don't have to do that because there are 2 triangles with the same base and height so you don't have to divide it by 2. 3 x 4 = 12, so A. 12 square feet is your answer.

Answer:

5 2/3 divided by 2 2/3 = 17/3 divided by 8/3 = 17/8 = 2 1/8 miles per hour

2 2/3 divided by 5 2/3 = 8/3 divided by 17/3 = 8/17 hours per mile

Answer:

1092

Step-by-step explanation:

(12x34) x 2 + (12x3) x2 + (34x3) x2 = 408 x 2 + 36 x 2 + 102 x 2

=816 + 72 + 204

= 1092

Answer:

Given The base of a rectangular prism has an area of 12 sq cm. The height of the rectangular prism is 3 cm

Now volume of the rectangular prism is given by length x width x height

Also area of rectangular prism is 12 sq cm and height of the rectangular prism is 3 cm.

But area of rectangle is length x width

Now volume of the rectangular prism           V = 12 cm^2 x 3 cm         V = 36 cm^3Therefore volume of the rectangular prism will be 36 cm^3

Answer:

Step-by-step explanation:

Volume of rectangular prism=w x h x l

V=12cm^2 x 3 1/3

V=12cm^2 x 1

V=12cm^3

Step-by-step explanation:

Answer: x= 385/12

Step-by-step explanation:

You would first change the denominator to some number that is common. Then combine the like terms. Lastly, subtract the fraction from the equal and you get your x.

[tex]\frac{13}{4} +\frac{1}{6} +x=\frac{71}{2} \\(\frac{39}{12})+(\frac{2}{12})+x=\frac{426}{12} \\\frac{41}{12}+x=\frac{426}{12} \\x=\frac{385}{12}[/tex]

Answer:

0

This is because for a number to be divisible by 9 all the digits should add up to a number divisible by 9. Since they already do you just put a 0.

same, i want the answer for the same question pls answer

Answer:

I think the volume is 31.5.

Step-by-step explanation:

Since you didn't include the original numbers for the base area, I just square rooted 9 because there's no other number other than 1 that you would multiply to get 9. Since volume is L*W*H I put 3 for the w and h (because 3*3 is 9) and then I multiplied 9 by 3.5 or 3 and 1/2 (the same thing) to get 31.5. So the volume is 31.5.

Answer:

I think the volume is 31.5.

Answer:

  √689 ≈ 26.2 leagues

Step-by-step explanation:

For the purpose of calculating the distance between the marked points, the line is considered to be the hypotenuse of a right triangle. The horizontal distance between the points is one leg of the triangle, and the vertical distance is the other leg. The Pythagorean theorem relates these distances.

The Pythagorean theorem relates right triangle sides 'a' and 'b' to hypotenuse 'c' with the formula ...

  c² = a² +b²

Taking the square root, we have an expression for 'c' in terms of 'a' and 'b'.

  c = √(a² +b²)

The horizontal distance between the points is the difference of their x-coordinates:

  a = x2 -x1 = 2 -(-18) = 20

The vertical distance between the points is the difference of their y-coordinates:

  b = y2 -y1 = -10 -7 = -17

When we square these numbers, we find their signs to be irrelevant.

  c = √(a² +b²) = √(20² +(-17)²) = √(400 +289) = √689

  c ≈ 26.249

The distance between the given points is about 26.2 leagues.
