The angles of a triangle are in the ratio 2 : 4 : 3, then find the angles.

Answer»

Given the ratio of the angles of a ’ triangle are 2 : 4 : 3.

2x : 4x : 3x

Sum of the angles of a triangle is 180°.

⇒ 2x + 4x + 3x = 180°

⇒ 9x = 180°

⇒ 9x/9 = 180°/9

∴ x = 20°

Angles are

⇒ 2x : 4x :,3x

2(20°) : 4(20°): 3(20°)

40°: 80° : 60°

∴ Angles of a triangle are 40°, 80°, 60°.
