If the angles of a triangle are in the ratio of 2:3:4, then the difference of the measure of greatest angle and smallest angle is
40°
Let the angles of the triangle be 2x, 3x and 4x => Sum of angles = 2x + 3x + 4x = 180° => 9x = 180° => x =180/9=20° Difference between greatest and smallest angle = 4x − 2x = 2x = 2 × 20 = 40°
