Segment jk is tangent to circle p and circle q, what does jk equal?

and , tell me exactly how you got the answer, a reason for every little thing, because i know the answer, i just don't know how to get it. and if you could show a picture with all of your work on it in some easy way to understand, that would be very .

I'd be more than happy to do all of that, but I can't even start
until I see YOUR picture of the problem.  That will show me
if circle-P and circle-q are overlapping, just touching, separate
from each other, same size, different sizes, their radii, and where
the points J and K are.  THOSE are the little things I need to know
in order to get started.

You want to know the distance between J and K, but you haven't
given us one single distance or size of anything in the problem ...
nothing at all to work with.  That right there makes it impossible.
 

Where is the problem
