What is the length of the hypotenuse?​
erma4kov [3.2K]

Answer:

The answer is c = 17 feet

Step-by-step explanation:

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

<em>a </em>= 8 feet

<em>b </em>= 15 feet

<em>a</em>^2 = 8 * 8 = 64

<em>b</em>^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 <em>a </em>and <em>b</em>.

The square root of 289 equals 17

c = 17 feet
