Hi,
I have a circle, I know its radius. I have a point on its edge. Is there anyway to figure out what angle in degrees that is?


/  \
P  \
  
OX
  
\  /
\ /


yeah that's a fine ascii circle, so anyway, I'm interested in the angle formed between P, O, X. I know the coordinates of all 3, I just want to know the angle between them.
Thanks for any help
p.s.  the formatting keeps messing up the circle (not that it was that great to begin with, hope it's understandable)
