The ratio of the measure of the three angles is 5:7:8. Find the measure of the triangle.

Step-by-step explanation:

If the ratio of triangle = 5:7:8

Total ratio = 5+7+8 = 20

The sum of angle in a triangle is 180°

1st angle = 5/20 * 180 = 5 * 9 = 45°

2nd angle = 7/20 * 180 = 7 * 9 = 63°

3rd angle = 8/20 * 180 = 8 * 9 = 72°
