Answer:

Let the given angles of the triangle be 4x, 3x and 2x.

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

Therefore,

  • 4x+3x+2x = 180
  • 9x = 180
  • x = 180/9
  • x = 20

Hence, the angles of the triangle are -

  • 4x = 4×20 = 80°
  • 3x = 3×20 = 60°
  • 2x = 2×20 = 40°
