Answer» Correct Answer - Option 1 : 25° Given: (3 × supplementary angle) - (7 × complementary angle) =10° Formula Used/Concept used: Sum of complementary angle is 90° Sum of supplementary angle is 180° Calculation: Let the angle be x ⇒ {3 × (180° - x)} - {7 × (90° - x)} = 10° . ⇒ 540° - 3x - (630° - 7x) = 10° ⇒ 540° - 3x - 630° + 7x = 10° ⇒ 4x - 90° = 10° ⇒ 4x = 10° + 90° ⇒ 4x = 100° ⇒ x = 100°/4 ⇒ x = 25° ∴ The required answer is 25° |
