Ответ:
angle B = 12
Step-by-step 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
