Question

Determine seno, cosseno e tangente dos ângulos ∝ e β no
triângulo retângulo.

Answer 1

$\boxed{\begin{array}{l}\sf sen(\alpha)=\dfrac{9}{15}\\\\\sf cos(\alpha)=\dfrac{12}{15}\\\\\sf tg(\alpha)=\dfrac{9}{12}\\\\\sf sen(\beta)=\dfrac{12}{15}\\\\\sf cos(\beta)=\dfrac{9}{15}\\\\\sf tg(\beta)=\dfrac{12}{9}\end{array}}$
