The angles of a triangle are in the ratio 2: 6 : 4. Find the measurement of the 3 angles of triangle.	Select.
A) 90°  B) 60°  C) 20°  D) 30°  E) 80°
If the ratio of the three angles is 2:6:4, then the measures of these angles can be written as 2x, 6x and 4x. Also the sum of the three interior angles of a triangle is equal to 180°. Hence   2x + 6x + 4x = 180   Solve for x   12x = 180   x =15   The measures of the three angles are   2x =2 x15=30°   6x = 6 × 15= 90°   4x = 4 × 15 = 60°   60°
