Solve for the angles x and y

I really really need help this is for a big test

Step-by-step explanation:

step-1: find the sum of the polygon interior angles

=(7-2)×180°

=5×180°

=900°

step-2: find x

according to the question

113+112+123+168+99+148+x=900

=>773+x=900

=>x=900-773

therefore

x=127

according to the question

127+y=180

=>y=180-127

therefore

y=53

25

step-by-step explanation:

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
