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)?

Well SilverKnight, the angle measurements you calculated earlier in your solution and obtain the angular measurement (in degrees) between beam rays in the reflection, not from the origin nor from point A, I hope your calculations are correct.
