Question

Two angles of a quadrilateral are
each measure 75 degree and the other two are equal . What are the of their Angles

Answer 1

let the other 2 angles be 'x '
As we know that sum of the angle of quadrilateral is 360°
Then, La +Lb+Lc+Ld = 360°
75° + 75° +x° + x° =360°
150° + 2x° = 360°
2x° = 360°-150°
2x° = 210°
x° = 105°
So the value of 'x' is 105°
Therefore the other two angles 105°.
