    value of x+y

    In the figure below, FG is the bisector of the angle JFL. What is the value of x - y?
    I have a bisecting angle with x+20 on one side of the bisecting line and y+80 on the other. How do I figure this out when I am not given the angles degree?

    Well it would be nice if we could see the diagram.

    However from your description it seems that:

    x+20=y+80

    so:

    x-y = 80-20

    or:

    x-y = 60

    value of x-y diagram

    here is an attachment to that diagram. I know it is probably pretty easy but I just am not getting this geometry online course I have to take. Not enough examples etc. Let me know if you still think it is what you put, but that does make sense kind of.

    The answer is the same, that is what I assumed the diagram looked like.
