Question

What is the approximate length of the missing side of the right triangle shown?

Answer 1

In order to calculate the length of the missing side, since we have a right triangle, we can use the Pythagorean Theorem.

So we have:

`\begin{gathered} 9^2=x^2+5^2 \\ 81=x^2+25 \\ x^2=81-25 \\ x^2=56 \\ x=\sqrt[]{56} \\ x=7.48 \end{gathered}`

Rounding to the nearest tenth, the length is 7.5, so the correct option is the third one.
