2. The base of a ladder is 6 feet away from the wall. to the nearest tenth of a foot, how high is the top of the ladder from the floor?

1. Using the Pythagorean theorem:
c%5E2+=+a%5E2%2Bb%5E2 the hypotenuse is side c (x in this problem) and a = 12 and b = 9, so...
c%5E2+=+12%5E2%2B9%5E2
c%5E2+=+144%2B81
c%5E2+=+225 Take the square root of both sides.
c+=+15
The length of X is 15 units.
2. The answer to this question is...it depends on the length of the ladder, a critical piece of information that is not provided.
