Question

which angle is adjacent to ∠ced? ∠bec ∠aeb ∠bea ∠dec

Explanation:

Step1: Recall adjacent - angle definition

Adjacent angles have a common side and a common vertex and no common interior points.

Step2: Analyze angles around point E

For \(\angle CED\), \(\angle BEC\) shares a common side \(EC\) and the common vertex \(E\) and no common - interior points.

Answer:

\(\angle BEC\)
