Question

Three angles which add up to 180 are in the ratio 2:3:7. find them

Answer 1

Ratio of three angles = 2 : 3 : 7

Let first angle be = 2x

Second angle = 3x

And third angle = 7x

∴ 2x + 3x + 7x = 180°

⇒ 12x = 180° ⇒ x = 180°/12 = 15°

∴ First angle = 2x = 2 × 15° = 30°

Second angle = 3x = 3 × 15° = 45°

and third angle = 7x = 7 × 15° = 105°

Hence, angles are 30°, 45° and 105°
