A light ray strikes a plane mirror lying flat on a horizontal floor, making an angle of incidence of 64.9°. After reflecting from the mirror, the ray makes a spot on a vertical wall. The wall is a horizontal distance d= 1.26 m from the point of reflection, as shown. How high from the floor is the spot on the wall? (Neglect the thickness of the mirror.)
