Please help, thank you!

Answer 1

Answer is D.

Explanation: if you draw a line from E to the other side, you can fine the missing angle. C=57 the corner we made with the line= 90. If you minus those from 180, you’ll get 33. And since we drew that line, A-E is now 90 degrees. If you plus 90 and 33, it gives you 123 degrees. There for AED=123 degrees.
