# If three angles of a triangle are in the ratio 2:3:5, determine three angles.

Let the given angles of a triangle be 2x, 3x and 5x.

We know that the sum of the angles of a triangle is 180°.

⇒ ∠A + B + C = 180°

2x + 3x + 5x = 180°

10x = 180°

x = 18°

So, A = 2× 18° = 36°

B = 3× 18° = 54°

C = 5× 18° = 90°
