To find the linear pair of ∠MRJ, we need to identify two angles that are adjacent and form a straight line, which means they sum up to 180°.

Looking at the diagram:
- ∠MRJ is angle 3. It is formed by the intersection of lines \( RM \) and \( JK \) at point \( R \).
- The angle adjacent to ∠MRJ, on the same straight line (along \( JK \)), is angle 2. Together, these two angles form a straight line, so they are a linear pair.

Thus, the angle number representing the linear pair of ∠MRJ is **2**.

Would you like more details on this solution? Here are 5 related questions to help expand your understanding:

2. What is the sum of the angles in a linear pair?
3. How do vertical angles relate to linear pairs?
4. Can an angle form more than one linear pair at an intersection?
5. How would you identify supplementary angles in this diagram?

**Tip:** Linear pairs always sum to 180°, which makes them supplementary by definition.
