Answer:
x = 10
y = 15
Step-by-step explanation:
Angles 8x - 10 and 7x are congruent because they are alternate interior angles of parallel lines cut by a transversal.
8x - 10 = 7x
x = 10
7x = 7(10) = 70
6y + 20 and 7x are supplementary since they are a linear pair.
6y + 20 + 7x = 180
6y + 20 + 70 = 180
6y = 90
y = 15
