Question

Aplicar lei dos senos/lei dos cossenos ,para encontrar o x .​

Answer 1

$\frac{ x}{ \sin(60) } = \frac{8}{ \sin(45) } \\ \frac{x}{ \frac{ \sqrt{3} }{2} } = \frac{8}{ \frac{ \sqrt{2} }{2} } \\ \frac{ \sqrt{2} x}{2} = \frac{8 \sqrt{3} }{2} \\ x = \frac{8 \sqrt{3} }{ \sqrt{2} } \\ x = \frac{8 \sqrt{3} }{ \sqrt{2} } \times \frac{ \sqrt{2} }{ \sqrt{2} } \\ x = \frac{8 \sqrt{6} }{2} \\ x = 4 \sqrt{6}$
