Question

In the figure below, N is between M and O, and O is between N and P. If MP= 17, NP = 15, and NO=7, find MO.

Answer 1

• MO = 9 units

------------------------------

As per question we have:

• Point N is between M & O and point O is between N & P. It means M and P are endpoints and the order of the points is M, N, O and P.

Find the required segment length using segment addition rule:

• MP = 17, NP = 15 ⇒ MN = MP - NP = 17 - 15 = 2, then
• MN = 2, NO = 7 ⇒ MO = MN + NO = 2 + 7 = 9
