Two plane mirrors are inclined to each other at an angle 60^(@) if a ray of light incident on first mirror parallel to the second mirror, it is reflected from the second mirror

Two plane mirrors are inclined to each other at a certain angle.A ray of light first incident on one of them at an inclination of 10^(@) with the mirror retraces its path after five reflections.The angle between the mirrors is

Two plane mirros are inclined to each other at an angle 60^(@) if a ray of light incident on firs tmirros paralell to the second mirror, it is reflected formt the second mirror

Two plane mirrors are inclined to each other such that a ray of light incident on the first mirror and parallel to the second is reflected from the second mirror parallel to the first mirror. Determine the angle between the two mirrors:
