What is the length of ef and the measure of ∡d?me : ( in the image below, δabc ≅ δdef.

The given information tells you that you have two congruent triangles. That means that all of the side lengths and angles will have the same measurement. So if the length of line CB is 10, then the length of the equivalent side of the second triangle (EF is also 10). Angle A and Angle D will also have the same measurement. Therefore, measurement of angle D is also 37 degrees.
