I cannot for the life of me, figure out what my math teachers are asking of me when they give me this problem. I havent the slightest clue how to figure this out. I was hoping that one of ya'll here would be a math wiz and help me out some.

Here is the problem, just show me how to get the answer PLEASE!!

If If angle a=2 angle x and angle b=2 angel y, what must be added to the hypothesis so that we may correctly dedue angle a = angle b???

I have no idea how to figure this out. Its not in my math book and Im stuck here. Help please.
