Determine , em radianos , a medida dos arcos de :

a)40°=

b)70°

c)20°

d)150°

e)240°

f)240°​

Answer 1

Resposta:

Olá bom dia!

Utilize π = 180° e faça a regra de três:

a)

π = 180

x = 40

180x = 40π

x = 40π/180

x = 2π/9

b)

π = 180

x = 70

180x = 70π

x = 70π/180

x = 7π/18

c)

π = 180

x = 20

180x = 20π

x = 20π/180

x = π/9

d)

π = 180

x = 150

180x = 150π

x = 150π/180

x = 5π/6

e)

π = 180

x = 240

180x = 240π

x = 240π/180

x = 4π/3

f)

π = 180

x = 240

180x = 240π

x = 240π/180

x = 4π/3
