Answer:
130
Step-by-step explanation:
The two angles with measurements are vertical angles and vertical angles are equal
12x-2 = 10x+20
Subtract 10x from each side
12x-10x -2 =10x-10x+20
2x-2 = 20
Add 2 to each side
2x-2+2 =20+2
2x= 22
Divide each side by 2
2x/2 =22/2
x =11
We want to find 2x-2
12(11)-2
132-2
