Since A and B are parallel lines, the two marked angles are congruent.
Then, 2x + 12 = x + 25
We can solve for x:
x = 13
The answer is x=13

The work: 2x+12=x+25 (subtract the 2x onto the other side) 12=-1x+25 (subtract 25 onto the other side) -13=-1x (divide the -1 with -13 like this -13/-1 over on the other side, leave the x) 13=x

I hope this helped! Brainliest? :) -Raven❤️
