Question

The triangles formed by two ladders leaning against a wall are similar. How long is the shorter ladder?

Answer 1

To solve this problem we must use proportions

`\begin{gathered} \text{ }(x)/(8)\text{ = }(42)/(24) \\ \text{ x = }\frac{8\text{ x 42}}{24} \\ \text{ x = }(336)/(24) \\ \text{ x = 14} \end{gathered}`

The length of the shortest ladder is 14.

letter B is the correct answer.
