Question

Calcule o seno , cosseno e tangente de 30, 45 , 60 , triângulo de (8 dos 3 lados )

Answer 1

$sen30=\frac{1}{2}\\ \\ sen45=\frac{\sqrt2}{2}\\ \\ sen(60)=\frac{\sqrt3}{2}\\ \\ cos30=\frac{\sqrt3}{2}\\ \\ cos45=\frac{\sqrt2}{2}\\ \\ cos60=\frac{1}{2}\\ \\ tg30=\frac{\sqrt3}{3}\\ \\ tg45=1\\ \\ tg60=\sqrt3$
