Question

Calcular o valor de x e y nesse triângulo retângulo

Answer 1

$\sin(30) = \frac{x}{5 \sqrt{3} } \\ \frac{1}{5} = \frac{x}{5 \sqrt{3} } \\ 5x = 5 \sqrt{3} \\ x = \frac{5 \sqrt{3} }{5} = \sqrt{3}$
$\cos(30) = \frac{y}{5 \sqrt{3} } \\ \frac{ \sqrt{3} }{2} = \frac{y}{5 \sqrt{3} } \\ 2y = 5 \times 3 \\ y = \frac{15}{2} = 7.5$
acredito que seja assim
