The angles of a quadrilateral are in the ration The measure of the largest angle is

Property - Sum of angles of a quadrilateral is equal to 360.


Let us consider the angle be x.


Therefore , the angles are x : 3x : 7x : 9x


Sum of angles = x + 3x + 7x + 9x = 360


20x = 360 → x = 18


Largest angle = 9x = 162 degree
