Sorry, let's try again Let segment PR cut C at point S bete This was a problem posed to me by a friend: Let circle C have center O. Let point P satisfy OP = 4. Draw tangent line L to C at point Q. Place point R on L with QR = 12. Let segment PR cut C at point S so that RS = 8 and RP = 12. What is the radius of C? Perhaps I got it right this time.
