Okay here is the question:
  1. A ladder 10 ft long leans against a wall. The bottom of the ladder is 6ft from the wall. How much would the lower end of the ladder have to be pulled away so that the top end would be pulled down the same amount?
What the heck are they asking for? I'm real good at math (Asian), but when you don't know what the question is trying to ask, it's hard to solve. Hope you guys can explain it in simple English. Thanks

As I understand it,

The ladder and the wall form a rt angled triangle with a base of 6 ft and hypotenuse of 10 ft (ht = 8 ft).

Now, by what length "x" would you increase the base of the triangle such that the ht of the new triangle is 8-x ft.

Most stereotypes are there because it's true.

dude, are you serious? that is easy as hell. tell me you are in HS.

anyway, it wants to know the remainder of one of the sides of an isometric triangle (only 2 sides) subtracted from 6 with a hypotenuse of 10.

Yes, I know, but at school I remember lots of anti-stereotype lectures and demonstrations :)

That's not even HS material...

that is not correct because it says the top pulled down by the same amount. i think it wants you to drag the ladder down so that both sides are equal length.

sounds like 9th grade geometry, but i see what you mean :)

imagine it in your mind... when you pull the lower end of the ladder away from the wall, the top end of the ladder kinda slides down... what they are asking is, how far would you have to pull the lower end away from the wall such that the ladder makes a triangle with the wall such that the inner angles are 45degrees each...

Not from how I read it.

find the movement from 6m where the top will move down the exact amount. So base = 6 + x and height = y - x. Solve for y via pythagorean thereom and then find x.

At least, thats how I read it.

I made the mistake that iamwiz made. I said x^2 + x^2 = 10^2

That just got me confused. All solved now. The answer, which was obvious from the beginning, is 2ft. Just needed to get the equation right.
