Solution
Given, angle between incident ray and mirror = 35o
(a). Angle of incidence = angle of mirror to the normal - angle between incident ray and mirror = 90 - 35 = 55o
(b). Angle of reflection = angle of incidence = 55o
(c). Total angle turned = angle of incidence + angle of reflection = 55 + 55 = 110o
(d). The angle between incident ray and reflected ray = Angle of incidence + Angle of reflection = 55 + 55 = 110o
