Answer:
69
70.5
84
Step-by-step explanation:
Firstly, we need to sort this list of numbers in order to perform calculations on it.
To find the mean we must add up and divide by the amount of numbers there are.
To find the median we must find the number in the middle of the set.
As there are two numbers in the middle positions, 69 and 72.
We must take the average of these two numbers to determine the middle.
The most is the most common number, which is 84.

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
