Question

Two angles are supplementary if the sum of their measures is 180°. find two supplementary angles such that the larger angle is 56° more than 3 times the smaller angle.

Answer 1

x = smaller angle

180 = x + (3x + 56)

180 = 4x + 56
124 = 4x
31 = x

smaller angle is 31 degrees

3 (31) + 56 = larger angle
149 = larger angle
