Question

which angle number represents the linear pair of ∠sxt?

Explanation:

Step1: Recall linear - pair definition

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

Step2: Identify adjacent angles to ∠SXT

∠SXT is an angle. Adjacent to it, the angle with non - common sides as opposite rays is ∠RXT. In the numbering of angles, if ∠SXT is considered, its linear pair is the angle adjacent to it on the straight line RS. Here, ∠SXT and ∠RXT are adjacent and form a straight line. If ∠SXT is angle 1, then ∠RXT is angle 2.
