Answer:

Angle BEC = 108°

Step-by-step explanation:

Vertical angles formed when two straight lines intersect are always congruent to each other. That is, the vertical opposite angles formed are of the same measure.

Angle AED = 108°

Angle AED and angle BEC are vertical opposite angles form by intersecting lines, therefore, angle AED = angle BEC.

Angle BEC = 108°
