find out distance from the mirror to the point where the reflected rays meet.

Two rays of light converge toward each other, as shown in the figure, forming an angle of = 28°. Before they intersect, they are reflected from the circular plane mirror with a diameter of D = 12 cm. If the mirror can be moved horizontally to the left or right, what is the greatest possible distance d from the mirror to the point where the reflected rays meet?
