Measure that angle IV (Posted on 2004-11-02)

Triangle ABC is isosceles with AB=AC. Point D is on side AB such that angle BCD is 70 degrees. Point E is on side AC such that angle EBC is 60 degrees. Angle ABE equals 20 degrees, and angle DCE equals 10 degrees.

Find angle EDC. Justify your answer.

Well, like, I carefully sketched the triangle and measured angle EDC. It's 20º ... I'm happy. Hugs. CeeAnne
