A ray of light encounters a pair of angled mirrors from the left, as shown, a distance d from one mirror and at an angle a from the other mirror. If angle a is exactly 22.5^{o}, how close will the ray get to their intersection at point O before it eventually exits again to the left? The drawing may not be to scale.
