1. The problem statement, all variables and given/known data In an amusement park maze with all the walls covered with mirrors, Pilar sees Hernando's reflection from a series of three mirrors. If the reflected angle from mirror 3 is 52° for the mirror arrangement shown in the figure, in which = 12°, what is the angle of incidence on mirror 1? 2. Relevant equations law of reflection: angle incident = angle reflected (with respect to normal) 3. The attempt at a solution Working backwards, I arrived at 40 degrees.
