Answer:
angle B = 58
Step-by-step explanation:
Complementary means that both angles add up to 90°.
Both angles are 9x-40 and 2x+42. Sum of both equal 90°
9x-40+2x+42=90
Combine like terms — we get:
11x+2=90
11x=90-2
11x=88
x = 8
Since we want to find angle B, substitute x = 8 in 2x+42
angle B = 2(8)+42
= 16+42
= 58
Therefore, angle B is 58.
