Step-by-step explanation:

Always draw out a diagram! Especially once you get to physics, its just best to be in the habit. There are a few ways we could solve this problem, but lets stick to the pythagorean theorem. a^2 + b^2 = c^2 .

a^2 + 64 = 289

a^2 = 225

a = 15

Therefore, the ladder reaches a height of 15 feet against the building.
