Question

The angles of quadrilateral are in the ratio 3:5:9:13. Find all the angles. ​

Answer 1

Answer:

Let the angles be x

Then, Ratio = 3x:5x:9x:13x

Sum of angles in quadrilateral = 360°

Then,

3x + 5x + 9x + 13x = 360°

30x = 360°

x = 360/30 = 12°

Then, angles are --

3x : 5x : 9x : 13x

3*12 : 5*12 : 9*12 : 13*12

36:60:108:156
