Question

se sen α √5/3 e cos α √4/3 qual o valor da tg α ?

Answer 1

$Tgx=\frac{Senx}{Cosx}$

 Então:

$Tg\alpha=\frac{Sen\alpha}{Cos\alpha}\\\\Tg\alpha\frac{\frac{\sqrt{5}}{3}}{\frac{\sqrt{4}}{3}}\\\\Tg\alpha=\frac{\sqrt{5}}{3}.\frac{3}{\sqrt{4}}\\\\Tg\alpha=\frac{\sqrt{5}}{2}$

Dúvidas só perguntar!
