    Try drawing your first normal to the glass at the point where XA enters...
    This diagram should help a little bit:

    Make sure you measure your angles correctly

    Thanks for the help Spartan and Fatone, but if you look at the diagram I posted, The incedent ray hits the glass at the corner, which is why I was having trouble with it. I can do the other shapes and sides for other refraction questions just this one I had trouble with the first normal. Thanks anyway!!

    The first normal is always (at this level) perpendicular to the glass at the point the light enters
    Basically in your example, the first normal can be thought to be the bottom the glass. Just draw in the angles and it works the same!
    It's quite a nice question actually :yes:
    No problem

    Thanks so much again my friend. My idea was to do what you are suggesting, but I wasn't sure what I was doing, but now I have your reassurance.
    Thanks again
