What is the length of the hypotenuse?​

The answer is c = 17 feet

Step-by-step explanation:

The formula to find the hypotenuse is a^2 + b^2 = c^2 (a squared plus b squared equals c squared).  

a = 8 feet

b = 15 feet

a^2 = 8 * 8 = 64

b^2 = 15 * 15 = 225

The next step is to add: 64 + 225 = 289

But we need to remember to square root 289 because we squared a and b.

The square root of 289 equals 17

c = 17 feet
