Question

HELPPPP ∠A and ∠B are complimentary. The measure ∠A is 42 more then 3 times the measurement of ∠B. Find ∠B

HELP PLZZZ

Answer 1

angle B = 12

Explanation:

angle A + angle B = 90 ( given they are complimentary )

Let us take the value of angle B as "x" and angle A as " 3x + 42"

3x + 42 + x = 90 (given that angle A is 42 more than 3 times angleB)

4x + 42 = 90

4x = 48

x = 48 / 4

x = 12

therefore, The value of angle B = 12
