Question

in the figure below, o is between m and p, and n is the mid - point of mo. if no = 5 and mp = 13, find op.

Explanation:

Step1: Find length of MO

Since N is the mid - point of $\overline{MO}$ and $NO = 5$, then $MO=2\times NO$.
$MO = 2\times5=10$

Step2: Find length of OP

We know that $MP=MO + OP$. Given $MP = 13$ and $MO = 10$.
$OP=MP - MO$
$OP=13 - 10$

Answer:

$3$
