What should be the angle of incidence of the beam so that the angle between the incident

What should be the angle of incidence of the beam so that the angle between the incident and reflected beams is equal to 50 ‘?

The law of reflection states that the angle of incidence of the beam is equal to the angle of the reflected beam. Since the angle between the incident and reflected rays is equal to the sum of the angles of incidence and reflection, we obtain that in this particular case the angle of incidence should be equal to:
50: 2 = 25 degrees.
