Im not sure how to set this up. I know that I will eventually have to use the sine/cosine laws.

Yeah.  So, the next step is drawing the chord in.  Basically we just need to know the definition of a chord to draw it in properly.

Yeah thats where im at a loss..

Basically, a chord is just a line segment that connects two points of the circle.  Examples:

So, a chord of length 6 in is just a little more specific, we draw in the chord that is 6 inches long.
