    something is missing. OP= l-AP but that's about all i can say and that it is the radius of the circle :x

    The question is complete and solvable. It was asked in one of our tests. Don't know the answer though, sorry.

    OP= L-AP... You have to state the unknowns with reference to the knowns...even if you can't quantify what they are. the length is known - L- OA is unown (it is L...L=OA) OP is both unknown and the focus of the equation that leaves AP which - whilst remaining unquantified - is the difference between OA (unknown) and OP (unknown)....you could also state for clarity OA-OP= AP....that way you are covering all bases!
