The angles of a triangle are in the ratio 1 : 2 :3 . Find the measurement of the 3angles of triangle.	Choices:
A) 100° B) 110° C) 60° D) 180° E) 190°
If the ratio of the three angles is 1:2:3, then the measures of these angles can be written as x, 2x and 3x. Also the sum of the three interior angles of a triangle is equal to 180°. Hence   x + 2x + 3x = 180   Solve for x   6x = 180   x = 30   The measures of the three angles are   x = 30°   2x = 2 × 30 = 60°   3x = 3 × 30 = 90°   60°
