B)
$\sqrt{1 - {n}^{2} }$
​

Answer 1

$\tt dados~\boxed{\begin{array}{l}\sf sen(\alpha)=M\\\sf cos(\alpha)=N\\\sf tg(\alpha)=? \end{array}}\\\underline{\rm soluc_{\!\!,}\tilde ao:}\\\sf tg(\alpha)=\dfrac{sen(\alpha)}{cos(\alpha)}\\\huge\boxed{\boxed{\boxed{\boxed{\sf tg(\alpha)=\dfrac{M}{N}}}}}\green{\checkmark}$
