Question

which angle number represents an angle adjacent to ∠mrj?

Explanation:

Step1: Recall the definition of adjacent angles

Adjacent angles have a common vertex and a common side.

Step2: Analyze \(\angle MRJ\)

For \(\angle MRJ\), at vertex \(R\), the angle \(\angle3\) shares the vertex \(R\) and the side \(RJ\) with \(\angle MRJ\).

Answer:

\(\angle3\)
