To help you with your questions about angles, I need more context or a diagram showing the relationships between the angles (EDC, ECD, CED, ECF, EFC, CEF) you've listed. Each angle's measurement typically depends on the configuration of points, lines, or geometric shapes surrounding them.
If you can provide information about any triangles, parallel lines, or other geometric figures involved, I would be glad to assist you in finding the measures of the specified angles.
