The angles of a triangle are in the ratio 4:6:8. Find the measurement of the largest of three angles of triangle.	Choose the correct choice from the following answers:
A) 80° B) 100° C) 120° D) 140° E) 160°
If the ratio of the three angles is 4:6:8, then the measures of these angles can be written as 4x, 6x and 8x. Also the sum of the three interior angles of a triangle is equal to 180°. Hence   4x + 6x + 8x = 180   Solve for x   18x = 180   x = 10   The measures of the three angles are   4x = 4 x 10° =40   6x = 6 × 10 = 60°   8x = 8 × 10 = 80°   80°
