Question

The ratio of the measures of the angles of a triangle is 4:6:8. Find the measure of the largest angle.

Largest angle?

Answer 1

80°

Explanation:

The angles can be written as 4x, 6x, and 8x. Since the sum of angles in a triangle is 180 degrees we can write:

4x + 6x + 8x = 180

18x = 180

x = 10 which means the largest angle (8x) = 8 * 10 = 80°
