Question

The ladder of a fire truck extends 41 ft. to the top of the

building. If the distance between the wall and the base of the
ladder is 9ft. How tall is the building?

Answer 1

Explanation:

By the Pythagorean Theorem a^2+b^2=c^2 or the sum of the squared sides is equal to the hypotenuse squared.

41^2=9^2+h^2

h^2=41^2-9^2

h^2=1600

h=40 ft
