A 10-ft ladder leans against the side of a house. The bottom of the latter is 5 ft from the side of the house. How high is the top of the ladder from the ground. If necessary, round your answer to the nearest tenth.

You can use the pythagreon theorum.

a^2 + b^2 = c^2

a^2 + 5^2 = 10^2

a^2 + 25 = 100

a^2 = 75

a = 5sqrt(3) = about 8.7

I hope this helped. :))))
