Angle A is a supplementary to Angle B. If < b = 65 degrees what is the value of x if < A = 5x -20 ?

x = 27

Step-by-step explanation:

Supplementary angles add up to 180 degrees

65 + 5x - 20 = 180

45 +5x = 180

5x = 135

x = 27

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
