The bottom of a ladder must be placed 5 feet from the building. The ladder is 14 feet long. How far above the ground does the ladder touch the wall?

hi

If your wall is straight , then. you have  a rectangular traingle.

As Pythagoras tells us :   wall² = ladder²- ground distance²

                                        wall² = 14²- 5²

                                         wall²   = 196 -25

                                        wall² = √171≈13,07

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
