The angles of a triangle are in the ratio 2:4:3. The smallest angle of the triangle is

  1. 20°
  2. 40°
  3. 50°
  4. 60°

Answer

The sum of the angles of triangle = 180°

Let the angles be 2x, 4x and 3x.

2x + 4x + 3x = 180°

9x = 180°

x = 20°

Smallest angle of triangle = 2x = 40°

The correct option is B.
