Question

What is the side of length of 15,6, and x?

Answer 1

Given:

From the above image,

Side length of 15 ft is the hypotenuse.

Side length of 6 ft is the leg.

To get the length of side x, we use the Pythagoras theorem.

`\begin{gathered} \text{hypotenuse}^2=\text{opposite}^2+\text{adjacent}^2 \\ 15^2=6^2+x^2 \\ 225=36+x^2 \\ 225-36=x^2 \\ 189=x^2 \\ x=\sqrt[]{189} \\ x=13.75 \end{gathered}`

Therefore, the side length of x is 13.75
