Question

the angles of x y z are in the ratio of X :Y : Z is equal to 4 :9 :5.find the magnitude of each angle​

Answer 1

therefore the no. of equal parts in the ratio is 4+9+5 = 18

angle 1:

4/18 × 180° = 40°

angle 2:

9/18 × 180° = 90°

angle 3:

5/18 × 180° = 50°

therefore the angles are: 40°, 90°, 50°.
