Two supplementary angles are in the ratio 7 : 8. Find the angles.

Question

KnowledgeBoat · Accepted Answer

Let angles be (7x)° and (8x)° Supplementary angles sum = 180° ∴ 7x° + 8x° = 180° ⇒ 15x° = 180° ⇒ x° = ⇒ x° = 12° Angles: (7x)° = (7 x 12)° = 84° (8x)° = (8 x 12)° = 96° Hence, the required angles are 84° and 96°.
