The diagram that represents the position of the fly is shown below

First, we would need the length from point A to the fly 

By Pythagoras Theorem

Distance from point A to the fly = [tex] \sqrt{8^{2}+ 1^{2} }= \sqrt{65} [/tex]

The length of the fly to the ceiling (AP)

AP = [tex] \sqrt{9^{2}- ( \sqrt{65} )^{2} } =4 m[/tex]
