Solução!

$Sen~60\º= \dfrac{ \sqrt{3} }{2}\\\\\\ Sen~30\º= \dfrac{1}{2}\\\\\\\\\ \dfrac{y}{10}= \dfrac{1}{2}\\\\\\\\ 2y=10\\\\\\\\ y= \dfrac{10}{2}\\\\\\\ \boxed{y=5m}$


$\dfrac{x}{10}= \dfrac{ \sqrt{3} }{2}\\\\\\\\ 2x=10 \sqrt{3}\\\\\\\\ x= \dfrac{10 \sqrt{3} }{2}\\\\\\ \boxed{x=5 \sqrt{3} }$

Bom dia!
