answered-by-expert Expert Answer
Let the angles of a quadrilateral be A, A+100, A+200 and A+300
 
Where A is the first angle and c.d is 100
 
Now, sum of the angles of a quadrilateral is 3600
 
Thus, A + A + 100 + A + 200 + A + 300 = 3600
 
4A + 600 =3600
 
4A = 3000
 
A = 750
 
Thus, angles are 750, 850, 950, 1050
