Answer:



Explanation:
Note:
- Linear pairs are two angles that are adjacent and add up to 180 degrees. They are formed when two lines intersect.
- Vertical angles are two angles that are opposite each other at an intersection of two lines. They are always equal in measure and supplementary.
- Supplementary angles are two angles that add up to 180 degrees. They can be linear pairs, but they do not have to be.
In this case:
a) Pair of angles that form a linear pair and supplementary angles are:
Note:
All linear pair angles are supplementary angles.
You can choose one from below:








Now,
b) pairs of vertical angles are:




So,
