Question Analysis:

This question involves the concept of adjacent angles in a geometric figure. The main focus is to identify an angle that shares a common vertex and a common side with angle 2.

 

Key Concept Explanation:

Adjacent angles are two angles that have a common vertex and a common side, and they do not overlap internally.

 

Step-by-Step Solution:

1. Analyze each option:

For ∠RKQ, it does not share a common side with angle 2, so it is not adjacent to angle 2.

For ∠RKB, it shares the common vertex K and the common side KB with angle 2, so it is adjacent to angle 2.

For ∠5, it does not share a common side with angle 2, so it is not adjacent to angle 2.

For ∠4, it does not share a common side with angle 2, so it is not adjacent to angle 2.
