you have a 15 foot ladder and need to reach exactly 9 feet up the wall. how far away from the wall should you place the ladder so that you can reach your desired location.



Answer :

To get the answer we can use pythagorean theorem.
a^2+b^2=c^2, where c is our 15 foot ladder and a is our 9 (no matther a or b)
We can substitute our data into eq
[tex]9^2+b^2=15^2 \\ 81+b^2=225[/tex]        /subtract 81 both sides
[tex]b^2=225-81 \\ b^2=144 \\ b=12[/tex] -
b=12 - its our answer
