M is the midpoint of PQ and N is the midpoint of PR, and O is the intersection of QN and RM, as shown. If QN\(\perp\)PR$, QN = 12, and PR = 14, then find OR.

QN = 12                PR = 14       PN = 7

 

F is a foot of the altitude from M to PN

 

Find angle QPN using QN and PN

 

Find QP and MP using the Pythagorean theorem

 

Find MF and PF using angle QPN and MP

 

Find angle MRF using MF and FR

 

And finally, find  OR  using NR and angle MRF

 

Good luck!  wink
