Wr know that sum of all angles in a quadrilateral is 360
Also the common difference is given 20 so let the angles be
a,a+20,a+40 and a+60
a+a+20+a+40+a+60= 360
4a+ 120= 360
4a= 240
a= 60
So the angles are
60,80,100,120 degrees
Hope it helped you

An in an AP if one is a then the next one will be a+20
