Question

Calcule seno, cosseno e tangente do ângulo alfa beta

Answer 1

Sendo CO o cateto oposto, CA o cateto adjacente e HI a hipotenusa temos:

$\sin = \frac{CO}{HI} \\ \\ \cos = \frac{CA}{HI} \\ \\ \tan = \frac{CO}{CA}$

$\sin \alpha = \frac{12}{13} \\ \\ \cos\alpha = \frac{5}{13} \\ \\ \tan \alpha = \frac{12}{5}$

$\sin \beta = \frac{5}{13} \\ \\ \cos \beta = \frac{12}{13} \\ \\ \tan \beta = \frac{5}{12}$
