Let common ratio be x So the angles will be 3x,5x,9x,13x As the angles add up to 360 in a quadrilateral Therefore, 3x + 5x + 9x + 13x = 360 30x=360 X =360/30 = 12 So,3x= 3 5x=60 9x=108 13x=256

Given ratio : 3:5:9:13

Let angles are 3x,5x,9x,13x

Sum of all angles of quadrilateral is 360.

So 3x+5x+9x+13x = 360

=> 30x = 360

=> x = 12

Then angles are : 36,60,108,156
