The goal is to find angle ADE.

I've tried a couple things.

EC = x, and EA = 3x, CD = 2y, and DB = 3y, and tried to find y and x using pythagorean theorum and law of cosines, but that didn't go very well.

I also tried setting that spot as O.

AOB = 180 - 30 - 30 = 120

EOD = 120 from vertical angles

DOB and EOA = 60, which made ODB = 110, and OEA as 100 degrees.

However, I couldn't figure it out from here.

Any suggestions or hints?

Thank you so much for your time,
