A 41-foot ladder is leaning against a building. The base of the ladder is 9 feet from the side of the building. How high does the ladder reach along the side of the building?
Answer provided by our tutors
let h = the height on the wall where the ladder reaches along the side of the building
the ladder, the base of the ladder and the side of building are sides of a right triangle
using the Pythagorean Theorem
h^2 = 41^2 - 8^2
by solving we find
h = 40.21 ft
