Explicação passo a passo:

$\mathsf{\dfrac{8}{sen\:30\textdegree} = \dfrac{x}{sen\:135\textdegree}}$

$\mathsf{\dfrac{8}{1/2} = \dfrac{x}{\sqrt{2}/2}}$

$\mathsf{4\sqrt{2} = \dfrac{x}{2}}$

$\boxed{\boxed{\mathsf{x = 8\sqrt{2}}}}$

$\mathsf{\dfrac{8}{sen\:30\textdegree} = \dfrac{y}{sen\:15\textdegree}}$

$\mathsf{\dfrac{8}{1/2} = \dfrac{x}{\sqrt{6}-\sqrt{2}/2}}$

$\mathsf{4(\sqrt{6}-\sqrt{2}) = \dfrac{x}{2}}$

$\boxed{\boxed{\mathsf{y = 8(\sqrt{6} - \sqrt{2})}}}$
