Question

Plsss help, I've been stuck on this problem for a while

find the measure of each marked angle​

Answer 1

x = 8, so the angles measure 60 degrees.

Explanation:

Alternate exterior angles are congruent, so we have:

`10x - 20 = 7x + 4`

`3x = 24`

`x = 8`

`10(8) - 20 = 80 - 20 = 60`

`7(8) + 4 = 56 + 4 = 60`
