Two plane mirrors intersect at right angles. a laser beam strikes the first of them at a point 11.5 cm from their point of intersection, as shown in fig. e33.1 for what angle of incidence at the first mirror will this ray strike the midpoint of the second mirror (which is 28.0 cm long) after reflecting from the first mirror?

The measure of one angle of an octagon is two times smaller that of the other seven angles. what is the measure of each angle?
