Geometry question for Isosceles Triangle

[steve123456]

Hi, this is my first post. I'm stumped on this question. Sorry there's no pic.

Let Triangle ABC be an isosceles triangle(AB=AC) with Angle BAC=20 degrees. Point D is on side AC such that Angle DBC=60 degrees. Point E is on side AB such that Angle ECB=50 degrees. Find, with proof, the measure of Angle EDB.

Can you please try to find a solution not involving trigonometry? Thanks.

It'll be very helpful to draw it out.

THANKS, ANDREW TOM!

I did this some time ago and recently came across a number of solutions as well as similar problems and their solutions here: http://www.cut-the-knot.org/triangle/80-80-20/index.shtml#Original

Hope this helps you.
