If I have a trapezoid with 2 bases, AD and CF, with base $AD=x+3$ and base $CF=36$, how do I find $x$ and $y$ if their median, $BE$, equals $x+y$?
Ive tried to use $BE=\frac 12(AD+CF)$, but that doesnt give me a numerical answer. And there is a numerical answer. I just cant find HOW to get it/THE WAY of getting it.
