The recommended angle for a firefighting ladder is 75 degrees. When a 110-foot ladder is put up against a building at this angle, the base of the ladder is about 28 feet from the building. The base of the ladder is 8 feet above the ground. How high on the building will the ladder reach?

right triangle ladder is hypotenuse (110 ft) one leg is 28 ft the other is the height

28^2 + x^2 = 110^2 x = height from truck = 106.38 ft

you must add the eight feet off of the ground to this 114.38 ft
