The angles of a triangle are in the ratio 3 : 1 : 2. The measure of the largest angle is 90° Let x be any number such that the three angles are (3x)°, (1x)°, and (2x)°.We know, the sum of the angles of a triangle is 180°.3x + 1x + 2x= 180⇒ 6x = 180 ⇒ x = `180/6` = 30 ∴ (3x)°= (3 × 30)° = 90°(1x)° = (1 × 30)° = 30°(2x)° = (2 × 30)° = 60° The measure of the largest angle is 90°.
