Question

Angle a and angle b are complementary. angle a = (5x+2)*. find angle b

Answer 1

complementary angles = 90⁰

so,

<A + <B = 90

(5x + 2) + <B = 90

<B = 90 - 5x - 2

<B = 88 - 5x

Answer 2

B = 88 - 5x

Explanation:

1. Represent angle B:

B = 90 - angle A

B = 90 - (5x + 2)

2. Since there is only one equation, there's no further way of finding a numerical answer.

Angle B = 88 - 5x.
