Question

determine o valor de X

Answer 1

A)    

$\frac{CO}{HIP} = Sen30°$

$\frac{6}{x} = \frac{1}{2}$

x = 12

B)

$\frac{CO}{CA} = Tang60°$

$\frac{8}{x} = \sqrt{3}$

Aplicando regra de três:

$\sqrt{3} . x = 8$

$x = \frac{8}{\sqrt{3}}$  → Agora racionalizando:

$x = \frac{8 \sqrt{3}}{3}$

C)

$\frac{CA}{HIP} = Cos60°$

$\frac{x}{12} = \frac{1}{2}$

x = 6
