Question

Find m
we learned this last week and I forgot, please help!

Answer 1

x=8

Explanation:

I think you mean find x, not m.

since angle DEG and angle GEF are a linear pair, they equal 180º.

18x-9 + 4x+13 = 180

22x + 4 = 180

subtract 4 from each side

22x = 176

divide each side by 22

x=8
