What is the angle of incidence at the first mirror

Reference no: EM13272699

A pair of flat mirrors meet to form a right angle. A beam of light is incident on one of them at a point 11.5 cm from their point of intersection. If the beam reflects and then strikes the midpoint of the second mirror(which is 28.0 cm long), what is the angle of incidence at the first mirror?
