The Deep Dive
To find how high the ladder reaches on the wall, we can use the Pythagorean theorem. The ladder, the wall, and the ground create a right triangle where the ladder is the hypotenuse. We have:
Here,
ft (length of the ladder),
ft (distance from the wall), and we need to find
(height up the wall).
Plugging in the values:
Now taking the square root:
So the ladder reaches
ft up the wall, which simplifies to
ft.
The ladder reaches
ft above the ground.
