Find the value of x.

13 degrees.

Step-by-step explanation:

Due to the vertical angles theorem, it states that if two angles share a vertex then they are congruent. In this case, they are since they share a vertex so, the value of x is 13 degrees.

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
