Answer:
5
Explanation:
The angle number that represents the linear pair of ∠TYW is 5.
This is because, a linear pair is a pair of adjacent angles formed when two lines intersect whose sum is equal to 180 degrees.
The number representing ∠TYW is 4.
So the number that is adjacent to angle TYW and adds up to 180 degrees (a straight line) is 5 also known as Y, since it's vertical to Y(vertical angles always equal the same measure).
