Question

Find each of the missing sides of the right triangles using Pythagorean Theorem.

Answer 1

We need to apply the Pythagorean Theorem, which says that the square of the Hypothenuse is equal to the sum of the squares of the cathetus. So we have:

`\begin{gathered} 41^2=x^2+9^2 \\ 1681=x^2+81 \\ x^2=1681-81 \\ x^2=1600 \\ x=\sqrt[]{1600} \\ x=40 \end{gathered}`

The missing side is equal to 40.
