Answer:
126.6 ft
Step-by-step explanation:
I've attached a picture. Look at the right triangle. A side is missing. Use the Pythagorean Theorem to find it.
(leg)^2 + (leg)^2 = (hypotenuse)^2
[tex]x^2+9^2=94^2\\x^2+81=8836\\x^2=8755\\x=\sqrt{8755}\approx93.6[/tex]
The ladder touches the wall at a height of 93.6 ft. Now add the 13 "extra" feet from the top of the ladder to the top of the building.
The building is 126.6 ft tall.
