Question

In the figure below, N is between M and O, and O is between N and P . If MP=16, NP=13 , and MO=9 , find NO.

NO= ?

Answer 1

MP = 16 ,, where NP = 13

therefore : MP - NP = MN <=> MN = 16 - 13 <=> MN = 3

MP = 16 ,, where MO = 9

therefore : MP - MO = OP <=> 16 - 9 = MO <=> MO = 7

MO = 7 & MN = 3

therefore : MO - MN = NO <=> NO = 7 - 3 <=> NO = 4
