Explicação passo a passo:

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

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

$\mathsf{16 = \dfrac{2x}{\sqrt{2}}}$

$\mathsf{16 = \sqrt{2}\:x}$

$\mathsf{x = \dfrac{16}{\sqrt{2}}}$

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