ABC is a triangle. D is a point on AB and E is a point on AC. ABC is equal to 20 degrees. DBE=20, EBC=60, DCB=50, ECD=30. Find DEB?

P.S: All those are angles.

are you sure $\displaystyle \angle ABC$ and $\displaystyle \angle DBE$ both are 20 degrees?

You mean angle BAC = 20 degrees, not angle ABC, right? If so, go see my "geometry puzzle" here:

Oops! Sorry. Yes, it is BAC and not ABC. Anyway, thanks for the solution!
