Answer:
17
Explanation:
To find the hypotenuse, you would use the Pythagorean theorem.

We can plug 8 and 15 into A and B\

We can simplify this to
64+225=

289 =

To get C by itself not squared, we can do the square root of both sides.

If we simplify, we get
17 = C or C = 17
Therefore the length of the hypotenuse is 17.
