Question

determine o valor de tg 2130°

Answer 1

Explicação passo-a-passo:

$\blue {{ _{\heartsuit} } \heartsuit_{\heartsuit} } \: \: \mathsf {OI, TUDO \: \: J\acute{O}IA \: ? \: \:\blue {{ _{\heartsuit} } \heartsuit_{\heartsuit} } }$

$\mathtt{ \tan(2130°) } \\ \mathtt{ \tan(150° + 11 \times 180°) } \\ \mathtt{ \tan(150°\cancel{\blue { + 11 \times 180°}}) } \\ \mathtt{ \tan(150°) } \\\red{\mathtt{ - \frac{ \sqrt{3} }{3} }} \\ \mathtt{ou} \\ \red{\mathtt{ \approx - 0,57 }}$
