----------------------------------------------------------------------------------------------------
$sen 30= \frac{y}{6}$
$\frac{1}{2}= \frac{y}{6}$
$2y=6$
$y=\frac{6}{2}$
$y=3$
----------------------------------------------------------------------------------------------------
$sen30= \frac{x}{10}$
$\frac{1}{2}= \frac{x}{10} 2x=10$
$x= \frac{10}{2}$
$x=5$
----------------------------------------------------------------------------------------------------
RESPOSTA: x=5     y=3
