Se [tex]\pi[/tex] é igual a 180°, Então,
[tex] \frac{3\pi}{4} =~ \frac{3.180\°}{4} =135\°[/tex]
[tex] \frac{7.\pi}{6} =~ \frac{7.180\°}{6} =210\°[/tex]
[tex] \frac{\pi}{6} = \frac{180\°}{6} =30\°[/tex]
[tex] \frac{3\pi}{4} =~ \frac{3.180\°}{4} =135\°[/tex]
[tex] \frac{7.\pi}{6} =~ \frac{7.180\°}{6} =210\°[/tex]
[tex] \frac{\pi}{6} = \frac{180\°}{6} =30\°[/tex]
