The angle between the beam and the perpendicular drawn to the mirror at the point of incidence of the beam was 0 degrees. By turning the mirror, we changed this angle, now it is 60 degrees. Consequently, the reflected beam will also move away from the perpendicular by 60 degrees. Total 120 degrees.
