Answer :


We know that the sum of the angles in a Quadrilateral is 3600.


Let us consider Quadrilateral ABCD,


Let A = 700 and B = 1300 ,


According to the problem, it is told that the remaining two angles are equal,


i.e, C = D


A + B + C + D = 3600


Now substituting the values and conditions we get,


700 + 1300 + C + C = 3600


2000 + 2 × C = 3600


2 × C = 3600 - 2000


2 × C = 1600



C = 800


The values of the other two angles is700, 700.
