Question

An angle measures 118° less than the measure of a supplementary angle. What is the measure of each angle

Answer 1

Supplementary angles add up to 180°

x = greater supplementary angle
x - 118 = lesser angle

x + (x - 118) = 180
2x - 118 = 180
2x = 298
x = 149

x - 118
149 - 118 = 31

the angles are 31° and 149°
