Question

qual o valor de x na figura ​

Answer 1

Resposta:

x= 3√3

Explicação passo-a-passo:

usando o cosseno

cos30°=CA/H ->  √3/2= x/6

2x= 6√3

x= 6√3/2

x=3√3

Answer 2

Oie, Td Bom?!

$\cos(θ) = \frac{Cateto \: Adjacente \: a \: θ}{Hipotenusa}$

$\cos(30°) = \frac{x}{6}$

$\frac{ \sqrt{3} }{2} = \frac{x}{6}$

$\sqrt{3} \: . \: 6 = 2 \: . \: x$

$6 \sqrt{3} = 2x$

$2x = 6 \sqrt{3}$

$x = \frac{6 \sqrt{3} }{2}$

$x = 3 \sqrt{3} \: m$
