Question

Determine seno, cosseno e tangente nos ângulos.

Answer 1

Explicação passo-a-passo:

$\sin( \alpha ) = \frac{9}{15} = \frac{3}{5} \\ \\ \cos( \alpha ) = \frac{12}{15} = \frac{4}{5} \\ \\ \tan( \alpha ) = \frac{9}{12} = \frac{3}{4}$

$\sin( \beta ) = \frac{12}{15} = \frac{4}{5} \\ \\ \cos( \beta ) = \frac{9}{15} = \frac{3}{5} \\ \\ \tan( \beta ) = \frac{12}{9} = \frac{4}{3}$
