Are you too tired to chase angles?

Geometry Level 3

Let ABC be an isosceles triangle \(AB=AC\) with \(\angle BAC = 20^{\circ} \). Point \(D\) is on side \(AC\) such that \(\angle DBC = 60^{\circ} \). Point \(E\) is on side \(AB\) such that \(\angle ECB = 50^{\circ} \). Find the measure of \(\angle EDB\) in degrees.
