Sun rays are incident at an angle of `24^(@)` with the horizon. How can they be directed parallel to the horizon using a plane mirror?

Sun ray are incident at an angle of 24^(@) with the horizon. They be directed parallel to the horizon using a plane mirror for this plane mirror should be placed at an angle :
