Question

Two angles of a quadrilateral are respectively 70 and 80 degrees. The other two angles are equal in measure.<br />Find the measure of the other two angles123

Answer 1

here sum of all angle of quadrilateral is equal to 360.
so a/q
70+80+2x=360
2x=360-150
2x=210
x=105

hence other two angles are 105 .

Answer 2

105degree , 105degree
