Answer:
[tex]y\approx75.0[/tex] is the correct answer.
Step-by-step explanation:
[tex]\tan \left(30^{\circ \:}\right)=\frac{x}{150}\quad :\quad x=50\sqrt{3}\quad \left(\mathrm{Decimal}:\quad x=86.6\dots \right)\\\\\sin \left(60^{\circ \:}\right)=\frac{y}{86.6}\quad \rightarrow\quad y\approx75[/tex]
