Question

Marvin has a 27-foot ladder. Safety standards

dictate that the base of a 27-foot ladder should be
placed 7 feet from a vertical wall. How far above the
ground will the top of the ladder be on the wall, in
feet? (Round your answer to the nearest tenth.)

Answer 1

15.17

Explanation:

Answer 2

15.1657508881 or 15.17

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!
