Let all the angles be 3k , 5k ,9k, and 13k
we know that the some of total angles in quadrilateral is 360 degrees
so adding up the angles

3k+5k+9k+13K=360
30k=360
k=360/30
k=12

hence 3k=3*12=36
5k=5*12=60
9k=9*12=108
13k=13*12=156
hence these are the angles

3x+5x+9x+13x=360
30x=360
x=360/30=12
the angles are 36,60,108,156
i hope this helps u
