Resposta :
a- sen x = 1/2 > sen x= 30 graus
b- cos x = 1/2 > cos x = 60 graus
c- tg x = raiz de 3 > tg x = 60 graus
d- sen x = raiz de 3/2 > sen x = 60 graus
resolva as equaçoes a seguir
a- senx=1/2
b - cosx=1/2
c- tgx= raiz de 3
d- senx= raiz de 3 /2
a- sen x = 1/2 > sen x= 30 graus
b- cos x = 1/2 > cos x = 60 graus
c- tg x = raiz de 3 > tg x = 60 graus
d- sen x = raiz de 3/2 > sen x = 60 graus
