Question

Find the length of the missing side. Round answers to the nearest tenth if necessary.

Answer 1

We can draw the following right triangle:

since, we have a right triangle, we can apply Pythagorean theorem:

$(\sqrt[]{2})^2+(\sqrt[]{2})^2=z^2$

which gives

$\begin{gathered} 2+2=z^2 \\ 4=z^2 \\ z=\sqrt[]{4} \\ z=2 \end{gathered}$

therefore, the missing side z is equal to 2.
