Question

A ladder leans against the side of a house. The top of the ladder is 8ft from the ground. The bottom of the ladder is 6ft from the side of the house. Find the length of the ladder. If necessary, round your answer to the nearest tenth.

Answer 1

Explanation

We can use Pythagorean theorem:

$\begin{gathered} x^2=6^2+8^2 \\ x^2=36+64 \\ x^2=100 \\ x=\sqrt{100} \\ x=10 \end{gathered}$

Answer

The length of the ladder is 10 ft
