Question

which angle number represents an angle adjacent to ∠jrm?

Explanation:

Step1: Recall adjacent - angle definition

Adjacent angles share a common side and a common vertex.

Step2: Identify angles at vertex R

At vertex R, angles ∠JRM and ∠MRK share side $\overrightarrow{RK}$ and vertex R. Angle ∠MRK is represented by ∠2.

Answer:

∠2
