nope, this is it..I had a similar problem a looong time ago, and received a proper answer. I have been trying to modify that answer to suit this question since it is a different angle that needs to be calculated..I'm having problems doing that..

It's a parallelogram, so \(2x+2y=180\)

Dividing by 2, we get \(x+y=90\), and so \(AED=180-90=90\)
