Question

what is an angle that is supplementary to \\( \angle bec \\)?

Explanation:

Step1: Recall the definition of supplementary angles

Supplementary angles are two angles whose sum is \(180^{\circ}\).

Step2: Identify the angle adjacent to \(\angle BEC\)

Looking at the figure, \(\angle BEC\) and \(\angle BED\) form a linear pair. A linear pair of angles is supplementary.

Answer:

\(\angle BED\)
