Question

A 104 foot ladder is leaned against a wall. If the base of the ladder is 40 feet from the wall, how high up the wall will the ladder reach?

Answer 1

96 feet

Explanation:

If we draw a picture, we can see that the shape resembles a right triangle.

Hypotenuse: 104

Base: 40

a^2 + b^2 = c^2

1600 + b^2 = 10816

b^2 = 9216

b = 96 ft
