Question

which angle is supplementary to \\( \angle 3 \\)?

Explanation:

Step1: Recall the definition of supplementary angles

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

Step2: Analyze the relationship between \(\angle3\) and \(\angle6\)

From the diagram, \(\angle3\) and \(\angle6\) form a linear pair. A linear pair of angles is supplementary. So \(\angle3+\angle6 = 180^{\circ}\).

Answer:

\(\angle6\)
