Sorry that took so long... couldn't find a pen+paper. Okay, the first step is to draw it out. Is this what you're trapezoid looks like? (in next post)

This is how I got that: you know what a trapezoid looks like, right? And the bottom line, the long one, is the base.

It says that the base is BC, so I made one angle B and the other C. Does that make sense so far?
