Question

questão 25 ajuda aí prfv​

Answer 1

Resposta:

$\sin(30) = \frac{x}{h} \\ \sin(30) = \frac{x}{100} \\ \frac{1}{2} = \frac{x}{100} \\ 2x = 100 \\ x = \frac{100}{2} \\ x = 50m \\ \\ \cos(30 ) = \frac{x}{h} \\ \cos(30) = \frac{y}{100} \\ \frac{ \sqrt{3} }{2} = \frac{y}{100} \\ 2y = 100 \sqrt{3} \\ y = \frac{100 \sqrt{3} }{2} \\ y = 50 \sqrt{3}$

• 2x - y

$2(50) - 50 \sqrt{3} \\ 100 - 50 \sqrt{3} \\ 50(2 - \sqrt{3} )$
