In the given figure, O is a point inside m a ΔMNP such that MOP = 90°, OM = 16 cm and OP = 12 cm. If MN = 21 cm and NMP = 90° then NP = ?

The ΔMOP is right angled at O so MP is hypotenuse


(MP)2 = (OM)2 + (OP)2


(MP)2 = (16) 2 + (12)2


(MP)2 = 400


MP = 20 cm


Δ NMP is right angled at M so NP is the hypotenuse so


(NP)2 = (21)2 + (20)2


NP = 29
