Answer:
Angle at which the first light ray hit the mirror is 30° (corresponding angles)
Sum of angle at which the first light ray hit the mirror and angle to the normal = 90°
90° - 30° = 60° angle with ray of light to the normal
Base on Law of reflection, ray of light is turned off the first mirror at
60° + 60° = 120° angle.
