<h3><em>Hey there today we will solve your problem,</em></h3>
Number 1
_______________
<h3>Definitions</h3>- Vertical angles - <em>either of two angles lying on opposite sides of two intersecting lines.</em>
<em />
- Linear Pair - <em>A linear pair is a pair of adjacent angles formed when two lines intersect.</em>
_______________
Now we can solve Number 1, there is one pair of Vertical angles being ∠5 and ∠3
_______________
Number 2
Since we know the definition of a Linear Pair we can solve this problem also, the only Linear Pair that we can choose out the ones give to us is ∠4 and ∠3, because they are adjacent.
_______________
- ∠5 and ∠3
2. ∠4 and ∠3
