Answer:

Explanation:

4x - 17 + 3x + 8 + x + 13 = 180

8x + 4 = 180

8x = 176

x = 22

<A = 4x - 17

<A = 4*22 - 17

<A = 88 - 17

<A = 71

============

<B = 3x + 8

<B = 3*22 + 8

<B = 66 + 8

<B = 74

============

<C = x + 13

<C = 22 + 13

<C = 35

A B and C add to 180 as they should.

I'm sorry, that's all I can do. No time.
