Answer 1

90

Explanation:

angle 1 and 4 are equivalent so:

3x - 160 = x + 20

_________________

3x - 160 = x + 20

+160 I +160

3x = x + 180

- x I - x

2x = 108

÷2 I ÷2

x = 90

Answer 2

x=90

Explanation:

3x-160 = x+20. Why you may ask? they are corresponding angles which makes them congruent. 2x = 180, so x = 90
