Question

Preciso de ajuda! Alguém sabe!?

Answer 1

Resposta:

$\sin( \beta ) = \frac{c.op}{hip} \\ \sin( \beta ) = \frac{12}{4 \sqrt{13} } \\ \sin( \beta ) = \frac{12}{4 \times 3.6}$

$\sin( \beta ) = \frac{12}{14.4} \\ \sin( \beta ) =0.83$

$\cos( \beta ) = \frac{c.adj}{hip} \\ \cos( \beta ) = \frac{8}{4 \sqrt{13} } \\ \cos( \beta ) = \frac{8}{4 \times 3.6}$

$\cos( \beta ) = \frac{8}{14.4} \\ \cos( \beta ) = 0.5$

$\tan( \beta ) = \frac{c.op}{c.adj} \\ \tan( \beta ) = \frac{12}{8} \\ \tan( \beta ) = 1.5$
