Question

The length of a ladder leaning against a building is 60 feet. The ladder hits the building at the top of the building. The distance to the building from where the ladder touches the ground is 15 feet. What is the height of the building to the nearest foot?

A. 38ft
B. 48ft
C. 58ft
D. 68ft

Answer 1

C. 58ft

Explanation:

An imaginary triangle is described here. The hypotenuse is 60, and one of the other sides is 15.

60*60=3600

15*15=225

3600-225=3375

sqrt3375=58.09

round that to get 58ft
