Math Problem Statement
In the diagram below, line v is perpendicular to line h, and the angle at B is 75 degrees. A light ray has angle of reflection equal to angle of incidence. Our convention is to consider the angle which is ≤ 90 degrees. A ray has initial angle of incidence with v of 50 degrees. It follows a path in which it next hits wall h, then s, and then v again. What will be the number of degrees of its angle of incidence with wall v this (second) time?
