Question

What is the length of the hypotenuse of a right triangle if the two other sides are of lengths 5 and 14?

Answer 1

`sqrt221`

Explanation:

To solve this problem you need to use the pythagorean theorem.
`a^2 + b^2 = c^2`
Where c is the hypotenuse and a and b are the other two sides.
This only works on a right triangle.
So we are going to substitue 5 for a and 14 for b
`5^2 + 14^2 = c^2`
Solve for c
`25 + 196 = c^2`
`221 = c^2`
`sqrt(c^2)=sqrt221`
`c=sqrt221`
