Question

A ladder is leaning against a wall. The top of the ladder is 999 feet (\text{ft})(ft)left parenthesis, f, t, right parenthesis above the ground. If the bottom of the ladder is moved 3\,\text{ft}3ft3, space, f, t farther from the wall, the ladder will be lying flat on the ground, still touching the wall. How long, in feet, is the ladder?

Answer 1

you badly messed up with the formula.can you take a picture and send

Answer 2

Answer:

9.486 feet

Step-by-step explanation:

The top of the ladder leaning against a wall is at height of wall = 9 feet

The bottom of Ladder is moved farther from wall= 3 feet

It Forms an right angled triangle

We are supposed to find  How long, in feet, is the ladder i.e. Hypotenuse

So, $Hypotenuse^2 = Perpendicular^2+Base^2$

$Hypotenuse^2 = 9^2+3^2$

$Hypotenuse =\sqrt{ 9^2+3^2}$

$Hypotenuse =9.486$

Hence the ladder is 9.486 feet long .
