Answer 1

Resposta:

a) π/6

b) π/9

c) 2π/3

d) 5π/4

e) 5π/3

f) 4π/3

g) 11π/6

Explicação passo-a-passo:

Uma volta completa equivale a 360° que equivale a 2π radianos.

Regra de três simples:

a) 30°

2π → 360°

x. → 30°

x.360 = 30.2π

x = 30.2π/360 = 3.2π/36 = 2π/12 = π/6

b) 20°

x = 20.2π/360 = 2.2π/36 = 2π/18 = π/9

c) 120°

x = 120.2π/360 = 12.2π/36 = 2π/3
