Question

Two angle of a triangle are in the ratio 3:6. If the sum of these angles is equal to the third angle. Find the angles of the triangle.​

Answer 1

The answer is 30°,60°,90°

If we add all the angles of a triangle, we will get 180°

3 + 6 = 9

3 + 6 + 9 = 18

180 ÷ 18 = 10

3×10 + 6×10 + 9×10

30° + 60° + 90° = 180°
