Question

Expresse em rad:
a) 210°
b)150°
c)12°
d)2°​

Answer 1

Explicação passo-a-passo:

a) 210°

180°/210°=π/x

180x=210π

x=210π/180 = (210π÷30)/(180÷30)

x= 7π/6

b)150°

180°/150°=π/x

180x=150π

x=150π/180=(150π÷30)/(180÷30)=

x= 5π/6

c)12°

180°/12°=π/x

180x=12.π

x=12π/180 =(12π÷12)/(180÷12)

x=π/15

d)2°

180°/2° = π/x

90= π/x

x=π/90
