Question

Two angles of a quadrilateral are 50 and 70 and other two angles are in the ratio 13:11 find their measures

Answer 1

sum of all angles of a quadrilateral =360 degree

so, take angles

50+70+13x+11x= 360

120+24x=360

24x=360-120

24x=240

x=240/24

x=10

therefore,

13x=13*10=130

11x=110
