Question

what is an angle that is supplementary to \\( \angle 4 \\)?

Explanation:

Step1: Recall the definition of supplementary angles

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

Step2: Identify the angle adjacent to \(\angle4\)

Looking at the diagram, \(\angle4\) and \(\angle5\) form a linear pair. By the linear - pair postulate, angles in a linear pair are supplementary.

Answer:

\(\angle5\)
