\(\Rightarrow \mathrm{s}=\frac{\mathrm{u}^{2}}{2 \mathrm{a}}=\frac{\mathrm{u}^{2}}{2 \mathrm{gsin} \theta}\)

\(\frac{\mathrm{x}_{1}}{\mathrm{x}_{2}}=\frac{\sin \theta_{2}}{\sin \theta_{1}}=\frac{\sin 30^{\circ}}{\sin 60^{\circ}}=\frac{1 / 2}{\sqrt{3} / 2}\)

\(\Rightarrow \frac{x_{1}}{x_{2}}=\frac{1}{\sqrt{3}}\)
