Two plane mirrors (shown to the right) both stand perpendicular to the floor and meet at the angle $\theta = 17^\circ.$ A laser beam is pointed at one of the mirrors such that the beam travels parallel to the other mirror and to the floor.

At how many points will the light be reflected by the two mirrors?


Clarification: The figure shows the top view of the two mirrors and the laser beam.
