Circle problem
I went halfway, than I got stuck.
Question:Find the cord AB
I drew in my own line, OC and found the length of that, than I found the length of PB

$8sin65=OC$
$OC=7.254046...$

$8cos65=PC$
PC=3,380944...

$cos^-1(OC/11)=O$
$O=49.741394...
$

$11sin49.741394=BC$
$BC=8.26914843$

Now how do I find the segment AP?

You don't actually need to find AP.

Hint: AB = 2BC
