Answer:

15.1657508881 or 15.17

Step-by-step explanation:

I believe you are supposed to use the hypotenuse of a right triangle equation

a2+b2=c2

Let's begin! 27 feet is the hypotenuse (the longest part of a right triangle)(c)

so 7*7 is equal to 49

and 27*27 is equal to 279

Now you put the numbers back into the equation

49+b2=279, Now let's solve for b

279-49=230 b2=230

230 squared is 15.1657508881

Hope this makes sense!
