Question

which angle number represents the linear pair of ∠mrj?

Explanation:

Step1: Recall linear - pair definition

Two angles are a linear pair if they are adjacent and their non - common sides are opposite rays.

Step2: Identify the linear pair of ∠MRJ

∠MRJ and ∠MRK are adjacent and their non - common sides RJ and RK are opposite rays. In terms of angle numbers, ∠MRJ is related to ∠1. The linear pair of ∠MRJ is ∠1.
