Expert Answer
Let OM = x
then MP = 13 - x
In ΔPAO right angle at A.
using Pythagoras theorem
PA2 + AO2 = PO2
PA2 = 132 - 52
PA = 12
In ΔAPM right angel at M
using Pythagoras
AM2 = -x2 + 26x - 25 ...(i)
In ΔAOM right angel at M
Using Pythagoras we get AM2 = 25 - x2 ....(ii)
Comparing (i) and (ii) we get x = 2.8
