Two complementary angles are in the ratio 4 : 5. Find the angles.

Question

KnowledgeBoat · Accepted Answer

Let angles be (4x)° and (5x)° Complementary angles sum = 90° ∴ 4x° + 5x° = 90° ⇒ 9x° = 90° ⇒ x° = ⇒ x° = 10° Angles: (4x)° = (4 x 10)° = 40° (5x)° = (5 x 10)° = 50° Hence, the required angles are 40° and 50°.
