Question

Angle A and B are supplementary angles. If m angle A = (6x + 10) and m angle B = (4x + 30), then find the measure of angle B.

Answer 1

angle A is 94

angle B is 86

Explanation:

supplementary angles add up to 180°

(6x + 10) + (4x + 30) = 180

10x + 40 = 180

10x = 140

x = 14

A is 94

B is 86
