The document describes a figure with a square ABCE and an equilateral triangle CDE. It asks to find the measure of angle EBD. Using properties of squares and equilateral triangles, angle CBD is found to be 15 degrees. Then, using the fact that interior angles of triangles sum to 180 degrees, angle EBD is calculated to be 30 degrees.
