Thread: Help required for Problem Sum on Applications of Trigonometry

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.

Do you understand what I did?

Thanks for your reply. I understand your method but I just felt that your method was more of a quadratic equation approach rather than trigonometric approach.

You will also need to show how you arrived at 12m height of the wall.
