The angles of a triangle are in the ratio 2: 3 : 4. Find the measurement of the 3 angles of triangle. Choose the correct choice from the following answers:  A) 75°  B) 25°  C) 40°  D) 80°  E) 20°
If the ratio of the three angles is 2:3:4, then the measures of these angles can be written as 2x, 3x and 4x. Also the sum of the three interior angles of a triangle is equal to 180°. Hence   2x + 3x + 4x = 180   Solve for x   9x = 180   x = 20   The measures of the three angles are   2x =2 x 2=40°   3x = 3 × 20 = 60°   4x = 4 × 20 = 80°   80°
