Question

transforme os angulos de graus 180 para radianos
a) 40°
b)100°
c)120°
d)225°
e)280°
​

Answer 1

É só multiplicar cada ângulo por (π/180)

a) 40(π/180) =

4π/18 =

2π/9 rad

b) 100(π/180) =

10π/18 =

5π/9 rad

c) 120(π/180) =

12π/18 =

2π/3 rad

d) 225(π/180) =

75π/60 =

25π/20 =

5π/4 rad

e)  280(π/180) =

28π/18 =

14π/9 rad
