$$\mathrm{Excuse}\mathrm{me}\mathrm{sir}...$$$$\mathrm{Why}\mathrm{is}\mathrm{it}\frac{2}{3}\left(2y\sin 60°\right)?\mathrm{I}{\mathrm{don}}^{\prime }\mathrm{t}\mathrm{understand}$$$$\mathrm{why}\mathrm{you}\mathrm{put}\sin 60°?{\mathrm{Isn}}^{\prime }\mathrm{t}\mathrm{it}\mathrm{only}\frac{2}{3}\times 2y+y??$$

$$\frac{2}{3}\left(2y\sin 60°\right)+y=x$$$$\Rightarrow y(\frac{2}{\sqrt{3}}+1)=x$$$$\frac{x}{y}=1+\frac{2}{\sqrt{3}}.$$
