Question

URGENTE preciso de cálculos

expresse em radianos:

g)20°=
h)150°=
i)315°=

​

Answer 1

Resposta:

Oi!

Use regra de três.

π rad = 180°

g)

20° = x rad

180° = π rad

180x = 20π

x = 20π/180

x = π/9 rad

h)

150° = x rad

180° = π rad

180x = 150π

x = 150π/180

x = 5π/6 rad

i)

315° = x rad

180° = π rad

180x = 315π

x = 315π/180

x = 7π/4 rad
