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!
Suppose the ratio to be 3x:3x:6x then use sum of angles of triangle is 180. Then find x. After that substitute the value of x in the above ratios
