Question

aplique a lei dos senos (matemática)

Answer 1

$\frac{x}{sen 45} = \frac{5}{sen 60} -\ \textgreater \ \frac{x}{\sqrt{2}/2 } = \frac{5}{\sqrt{3} /2} -\ \textgreater \ \sqrt{3}x/2 = 5 \sqrt{2}/2 -\ \textgreater \ \sqrt{3}x = 5\sqrt{2}$ 

$x = \frac{5 \sqrt{2} * \sqrt{3} }{3} -\ \textgreater \ x = \frac{5 \sqrt{6} }{3}$
