Question

Among two supplementary angles, the measure of the larger l is 36 more than measures of smaller find their measures

Answer 1

Sol: Let the measure of the supplementary angles be x and (x + 36). ⇒ (x) + (x + 36) = 180° ⇒ 2x + 36 = 180° ⇒ 2x = 144° ⇒ x = 72° Therefore, measures of the supplementary angles are 72° and (72 + 36) i.e. 108°.
