Question

Two angles of a quadrilateral are 700

, 500 and the remaining two are equal. Find the measure

of these two angles.

Answer 1

Answer:

let the other two angle each be x

sum of all angles in a quadrilateral = 360

=> 70+50+x+x= 360

120+2x=360

2x=360-120

2x=240

x=120

=>The other two angle of the quadrilateral are each equal to 120
