Use the exterior angle theorem to find the value of x in the triangle below. A
x = 7

B
x = 5

C
x = 12

D
x = 15

A) x = 7

Step-by-step explanation:

7x + 1 + 7x + 6 + (180 - 15x) = 180

combine like terms:

-x + 187 = 180

subtract 187 form both side of the equation:

-x = -7

x = 7

its 4 because 2 times 2 is 4, if you double the number two you get four

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
