Question

Determine o valor das incógnitas​

Answer 1

$\cos(30) = \frac{10}{y} \\ y = \frac{10}{ \cos(30) } = \frac{10}{ \frac{ \sqrt{3} }{2} } = 10. \frac{2}{ \sqrt{3} }$

$y = \frac{20 \sqrt{3} }{3}$

$\sin(60) = \frac{y}{x} \\ x = \frac{y}{ \sin(60) } = \frac{ \frac{20 \sqrt{3} }{3} }{ \frac{ \sqrt{3} }{2} }$

$x = \frac{20 \sqrt{3} }{3} . \frac{2}{ \sqrt{3} } = \frac{40}{3}$
