Two points have polar coordinates as follows: θ=130°,r=.35 (point A) and θ=70°,r=.6 (point B). There is a surrounding circle, r=1, that acts as a mirror, and you wish to send a light ray from point A to point B by bouncing it once off the circle. What two alternative directions could you send it in (use an angular measure paralleling the θ coordinate it would have if directed from the origin)?

I am assuming that the light beam intersets the circle then bounces off the circle in 90 degrees. You can then draw a right triangle with the hypotinuse at the .2725 side. From here i dont know where to go.
