Question

I can't figure out the answer please help

Answer 1

x=23. if you add 7x-5 and x+1 it should add up to 180°.

Answer 2

x = 23

Explanation:

Since the lines m and n are parallel, then x+1 is complimentary to 7x-5, both of them forming a 180º angle:

x + 1 + 7x - 5 = 180

8x - 4 = 180

8x = 180 + 4

8x = 184

x = 184 / 8

x = 23
