Let us draw out the triangle below:

Given that


\arctan \frac{\sqrt[]{3}}{3}=\beta

Using the trigonometric identity for tan 30, where


\tan 30=\frac{\sqrt[]{3}}{3}

Therefore,


\beta=30\degree

The sum of angles in a triangle is 180°.

Therefore,


\begin{gathered} \alpha+\beta+90=180\degree \\ \therefore \\ \alpha+30+90=180 \\ \alpha=180-90-30 \\ \alpha=60\degree \end{gathered}

To get the sides of the triangle, let us apply the Trigonometric ratios:

Using the Sine Trig. ratio,


undefined
