Question

calcule o valor de X:
​

Answer 1

Resposta:

$\sin(60) = \frac{12}{c} \\ \frac{ \sqrt{3} }{2} = \frac{12}{c} \\ c = 8 \sqrt{3} \\ \\ \sin(30) = \frac{12}{h} \\ \frac{1}{2} = \frac{12}{h} \: \: \: h = 24 \\ \\ pitagoras \\ {24}^{2} = {8 \sqrt{3} }^{2} + {x}^{2} \\ 576 - 192 = {x}^{2} \\ 384 = {x}^{2} \\ \sqrt{384} = x \\ 8 \sqrt{6} = x$
