if angle between  incident ray and the reflected ray is 72 degree then angle of incidence,
i = 72/2 = 36 degree                  (because in reflection = angle of incidence)
r =  36 degree
and angle between incident ray and mirror = 90-36 = 54 degree ( as the angl eis fron the normal to the mirror)
