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 $\angle JRM$

$\angle JRM$ has vertex $R$ and sides $\overrightarrow{RJ}$ and $\overrightarrow{RM}$.

Step3: Find adjacent angle

$\angle 3$ shares vertex $R$ and side $\overrightarrow{RJ}$ with $\angle JRM$.

Answer:

$\angle 3$
