c) 4π

d) 11π/6

e) 5π/9

f) 11π/18

g) 19π/18

h) 11π/9

i) 13π/18

j) 7π/4

Explicação passo-a-passo:

Fazendo regra de três achamos as respostas:

a)180° --- π

210° --- x

180°x = 210π

x = 210π/180

x = 7π/6

b) 180°---π

150° --- x

x = 150π/180

x = 5π/6

c) 180 ---- π

720 ---- x

x = 720π/180

x = 4π

d) 180 --- π

330 ---- x

x = 330π/180

x = 11π/6

e) 180 --- π

100 --- x

x = 100π/180

x = 5π/9

f) 180 --- π

110 --- x

x = 110π/180

x = 11π/18

g) 180 --- π

190 --- x

x = 190π/180

x = 19π/18

h) 180 ---- π

220 --- x

x = 220π/180

x = 11π/9

i) 180 --- π

130 --- x

x = 130π/180

x = 13π/18

j) 180 --- π

315 --- x

x = 315π/180

x = 7π/4
