- Excuse me? Can you help me with something??
- I can't seem to figure out how tall the ladder is?? I have tried everything!!
- My dad ladder, he can't figure out how tall the ladder??
- uh ohh? I have the same problem, I have no idea how to solve that I have tried everything, could we work together.
- Sure, what can I help you with??
- maybe we should use the pythagorean theorem??
- ohh yeah I never tried that before!
- ok. so my dad wall is 12 ft tall and from the wall to the end of the ladder its 5ft. So I need to figure out how tall is my dads ladder?
- and my ladder is 15 ft tall and my ladder is leaning against the house that is 12 ft tall, how are we going to do this?
- ok, so your equation would be 12 squared plus B squared equals 15 squared.
- ok, so you would have to put everything squared, like 12 times 12 or 7 times 7.
- so I have to solve for B??
- ok I got it.
- yep,so my equation would be 12 squared(144) plus 5 squared(25) equals 169.
- then you find the square root of 169 which is 13. So my answer would be that my dads ladder is 13 ft tall.
- I got 144 plus B squared equals 225. I subtracted 144 from each side and 81. Now I find the square root 81 and its 9.
- So from my wall to the bottom of the ladders its 9 ft.
