Question

tangente: 150º,120ºe300º

Answer 1

tangente de 120 e 0,713. tangente de 150 e 1,022. tangente de 300 e 45,244.

Answer 2

$\boxed{tg(150^o)=\frac{sen(150^o)}{cos(150^o)}=\frac{\frac{1}{2}}{-\frac{\sqrt3}{2}}=-\frac{1}{\sqrt3}=-\frac{\sqrt3}{3}}$

$\boxed{tg(120^o)=\frac{sen(120^o)}{cos(120^o)}=\frac{\frac{\sqrt3}{2}}{-\frac{1}{2}}=-\sqrt3}$

$\boxed{tg(300^o)=\frac{sen(300^o)}{cos(300^o)}=\frac{-\frac{\sqrt3}{2}}{\frac{1}{2}}=-\sqrt3}$
