Question

two angles of quadrilateral are of measure 65 degree and the other two angles are equal what is the measure of either of these two angles

Answer 1

Sum of the angles of quadrilateral =360



Let the other same angles be x




Then, as two angles are equal, their sum = x + x = 2x



2x +65+65=360


2x=360-130


2x=230


x = 230 / 2


x=115 °



Therefore, other required angles are 115° and 115°.

I hope this will help you.

Answer 2

Let the other two angles be x, x
Sum of all the four angles of quadrilateral is 360.
65+ 65 + 2x = 360
2x = 360 - 130
x = 230/2
x = 115
The other two angles are 115, 115.
