Identify the sides of the right triangle relative to the angle we want to find. The side opposite the angle is given as \(\sqrt{3}\), and the adjacent side is 1.
Recall the definition of the tangent function in a right triangle: \(\tan(\theta) = \frac{\text{opposite}}{\text{adjacent}}\).
Set up the equation using the given side lengths: \(\tan(\theta) = \frac{\sqrt{3}}{1} = \sqrt{3}\).
To find the angle \(\theta\), take the inverse tangent (arctangent) of \(\sqrt{3}\): \(\theta = \tan^{-1}(\sqrt{3})\).
Use your knowledge of special angles or a calculator to determine that \(\tan^{-1}(\sqrt{3})\) corresponds to \(60^\circ\).
