Do you understand what I did?
Heres goes the question:
A ladder AB,of length 13m, rests against a vertical wallwith its foot on a horizontal floor at a distance of 5m from the wall. When the top of the ladder slips down a distance of x metres on the wall, the foot of the ladder moves out by x metres. Find the value of x.
Swift replies will be appreciated. Thanks in advance.
