Answer:
12x-17=139
8x+35=139
Step-by-step explanation:
The angles are vertical angles which means they are equal
12x-17 = 8x+35
Subtract 8x from each side
12x -8x-17 = 8x-8x+35
4x -17 = 35
Add 17 to each side
4x - 17 +17 = 35+17
4x = 52
Divide each side by 4
4x/4 = 52/4
x =13
12x-17 = 12(13) -17 = 156-17 =139
8x+35 =8(13) +35=104+35=139
