Since ∠1 and ∠2 are complementary...they add up to be 90°.
∠1 = (-2x + 54)
∠2 = (8x + 18) we add these two up
6x + 72 = 90 subtract 72 from both sides
6x = 18
x = 3 place the value of x into the ∠2 equation
(8x + 18) = 8(3) + 18 = 24 + 18 = ∠2 = 42°
Answer:

Step-by-step explanation:
15 / 9 = 1.6666666667
90? there’s a 45 degree angle at the bottom left and it looks like the same angle as x and y
