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.
