Question

what is an angle that is supplementary to ∠aeb?

Explanation:

Step1: Recall supplementary - angle definition

Two angles are supplementary if their sum is 180 degrees. In a linear - pair of angles, the two angles are supplementary.

Step2: Identify linear - pair with ∠AEB

∠AEB and ∠BEC form a linear pair (since they are adjacent angles on a straight line FC).

Answer:

∠BEC
