Answer:
10 ft
Step-by-step explanation:
By using the pythagorean theorem, we know that leg1 squared plus leg2 squared is equal to hypotenuse squared.

The correct answer is: 19.39
Explanation:
Given numbers:
22.10, 13.45, 25.10, 17.20, 19.10
Total numbers = 5

Now to find the average of the given sequence, follow these steps:
Step-1:
Add all the numbers to get the total sum:
22.10 + 13.45 + 25.10 + 17.20 + 19.10 = 96.95
Step-2:
Divide 96.95 by 5 to get the average number:

Hence the correct answer is 19.39.
