Question

which angle number represents the linear pair of ∠tyw?

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 the linear pair of ∠TYW

∠TYW and ∠UYW share a common side YW and their non - common sides YT and YU are opposite rays. In the given numbering of angles, ∠TYW is angle 4 and ∠UYW is angle 5.

Answer:

5
