A) \[90{}^\circ \]
B) \[45{}^\circ \]
C) \[135{}^\circ \]
D) \[60{}^\circ \]
Correct Answer: A
Solution :
As, \[\angle BMN+\angle DNM=180{}^\circ \] \[\angle PMN+\angle PNM=90{}^\circ \] \[\angle MPN=180{}^\circ -(\angle PMN+\angle PNM)=180{}^\circ -90{}^\circ \] \[\Rightarrow \] \[\angle MPN=90{}^\circ \]You need to login to perform this action.
