Q6 of 35 Page 3

In Fig. , find the measure of ∠MPN.

Sum of angles of a quadrilateral is 360°


In the quadrilateral MPNO


∠NOP = 45°, ∠OMP = ∠PNO = 90°,


Let angle ∠MPN is x°


∠NOP + ∠OMP + ∠PNO + ∠MPN = 360°


45° + 90° + 90° + x° = 360°


x° = 360° - 225° 


x° = 135°


Therefore ∠MPN is 135°
