Answer:
y = 31
Explanation:
Because of the two sets of parallel lines, angle 8x + 1 is supplementary to angle 27x + 4, and we can solve for x.
Also, angle 8x + 1 is congruent to angle y + 10, and we can solve for y.
8x + 1 + 27x + 4 = 180
35x + 5 = 180
35x = 175
x = 5
8x + 1 = y + 10
8(5) + 1 = y + 10
41 = y + 10
y = 31
