a 25 foot ladder leans against the wallit touches the wall 24 feet off the ground if you slide the base of the ladder back 10 feet off the ground how far does it slide down the wall?

Use the Pythagorean Theorem as I showed Jenny/Jeremy/you.
but there is an extra number
original position of foot of ladder
x^2+24^=25^
...
x = 7

so it moves out another 10 feet, so foot is 17 feet from wall
y^2 + 17^2 = 25^2
...
y^2 = 336
y = √336 = appr 18.3

well, it was up 24 feet and now is up only 18.3 feet,
so ....... ??
im confused how do u get 7
