Pls help me on #3. I been having trouble on this I’m not so good at math

I think the answer is 5 if I'm right

m∠vru = 80°

m∠urw = 15°

step-by-step explanation:

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.
