Let x be the distance from the base of the plateau to you. Draw the situation as shown: [Triangle]
Since x is the side adjacent the \(60^{\circ}\) angle and we are given the length of the side opposite the angle, then we can use the tangent ratio to write: \(\displaystyle{\tan{{60}}}°={o}{p}\frac{{p}}{{a}}{d}{j}=\frac{{50}}{{x}}\)
\(\displaystyle{x}=\frac{{50}}{{\tan{{60}}}}°\)
Use a calculator in DEGREE mode \(x \sim 28.9m\)
