Problem
Mirror A and mirror B intersect at an angle of 45∘. A beam strikes mirror A with an angle of incidence of 25∘, reflects to mirror B, reflects back to mirror A, and then exits the system. By how many degrees has the beam’s direction been rotated from its original path after these three reflections?
