Answer :


Given . Angles of a quadrilateral are in the ratio 1: 2:3:4


Solution .


Let any quadrilateral be ABCD


Then


Sum of all angles of quadrilateral is 360°


A + B + C + D=360°


If angle A,B,C,D are in ratio 1:2:3:4


Then,


1x + 2x + 3x + 4x =360°


10x=360°


x=


x= 36°


all angles are 1x,2x,3x,4x


Conclusion.


Angles are 36° , 72° , 108° , 144°
