Answer:
x = 8
Step-by-step explanation:
40 + 6x + 2 = 90 {Complementary angles}
Combine like terms
40+ 2 + 6x = 90
42 +6x = 90 {Subtract 42 form both sides}
6x = 90 - 42
6x = 48 {divide both sides by 6}
6x/6 = 48/6
x = 8
Note that ∠A + ∠B = 180°
Therefore:
(8x + 74°) + (2x + 56°) = 180°
Simplify:
10x + 130° = 180°
Subtract both sides by 130°:
10x = 50°
Divide both sides by 10:
x = 5
Plug x into ∠B:
∠B = 2(5) + 56° = 10 + 56° = 66°
