what about this one @Fruitbasket

anonymous · Answer

Not sure about this one. The only thing I can think of is that AE is half the length of AC, or AD is half the length of AB, but that's not one of the answers :S

Is there any information about any of the other edges?

anonymous · Answer

No I don't think so !

I don't think you can answer it without knowing both sides AB and AC.
