The measures of the angles of triangle xyz ar in the ratio 3: 3: 6.what are the measures of the angles.

Angles in a triangle add up to 180°, so you can say that xyz = 180. 3 + 3 + 6 = 12, and 180 ÷ 12 = 15. Now, you just multiply 15 by each ratio value, so 15 × 3 = 45, 15 × 3 = 45, and 15 × 6  = 90, so these are the answers. I hope this helps!

The answer is part a: use
