Answer:
H
Step-by-step explanation:
When 2 parallel lines are cut by transversal, it creates 4 pairs of equal angles.
If you see the top "cutting" part, we can say "13x - 15" angle and the angle beside is a straight angle (180 degrees), so their sum is 180. Also, vertically with the "13x - 15" angle, there is another angle, that also creates a line, so their sum would be 180 as well.
Now, the angle "22x + 9" goes same in the below part of the "cutting" point. They are the same angles as the 4 angles on top "cutting" part.
Thus, we can say "13x - 15" and "22x +9" are corresponding angles and they are EQUAL in measure.
So, we can write the equation:
13x - 15 = 22x + 9
THen we can solve for "x".
Equation H is right.
