Will mark brainiest! what is the value of x?

enter your answer in the box.

45°

Step-by-step explanation:

All triangles are 180°.

So, we must first add up all of the other numbers:

80° + 55° = 135°

Next, we must find how much more we need to get to 180°:

180° - 135° = 45°

So, x = 45°

And, if you want to make sure. Just add up the numbers and make sure the sum is 180.

80 + 55 + 45 = 180

I hope this helps you out ; )

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

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right
