Question

A ladder leans against the side of a house. The top of the ladder is 14 from the ground. The bottom of the ladder is 10 from the side of the house. Find the length of the ladder. If necessary, round your answer to the nearest tenth.

Answer 1

17.2 to the nearest tenth.

Explanation:

Use the Pythagoras theorem

If x is the length of the ladder:

x^2 = 14^2 + 10^2

x^2 = 296

x = √296 = 17.2047
