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 that forms a linear pair with \(\angle BEC\)

A linear pair of angles is supplementary. The angle that forms a linear pair with \(\angle BEC\) is \(\angle AEC\) (because they are adjacent and their non - common sides form a straight line).

Answer:

\(\angle AEC\)
