Question

what is an angle that is supplementary to ∠jaf?

Explanation:

Step1: Recall supplementary - angle definition

Two angles are supplementary if their sum is 180 degrees. An angle supplementary to ∠JAF will form a linear - pair with it.

Step2: Identify the linear - pair angle

Looking at the diagram, the angle that forms a linear - pair with ∠JAF is ∠JAI since they share a common side (ray AJ) and their non - common sides (ray AI and ray AF) form a straight line.

Answer:

∠JAI
