Can you explain to me (detailed) on how to do this problem? I will give you a brainly if you get this right.

Answer:
see below
Step-by-step explanation:
Vertical angles are equal
2x = 68
Divide by 2
2x/2 =68/2
x = 34
20+160 = 180
And we know that supplementary angles add to 180
so 20 and 160 are supplementary angles
