The angles of a triangle are in the ratio 4:3:8. Find the measurement of the largest of three angles of triangle.  Options:
A) 96° B) 100° C) 120° D) 140° E) 160°
If the ratio of the three angles is 4:3:8, then the measures of these angles can be written as 4x, 3x and 8x. Also the sum of the three interior angles of a triangle is equal to 180°. Hence   4x + 3x + 8x = 180   Solve for x   15x = 180   x = 12   The measures of the three angles are   4x = 4 x 12° = 48   3x = 3 × 12 = 36°   8x = 8 × 12 = 96°   96°
