According to the law of reflection, the angle of incidence (the angle between the incoming light and the perpendicular to the mirror) is equal to the angle of reflection (the angle between the outgoing light and the perpendicular to the mirror). Therefore, the beam of light will reflect at an angle of 30° relative to a plane perpendicular to the surface of the mirror.
