Question

Oi, alguém poderia me ajudar?

Answer 1

a) 54/x = 180/π

180x=54*π

x=169,646/180

x=0,942 rad

R: 54° são 0,942 radianos

b)78/x = 180/π

180x = 78*π

x=245,044/180

x=1,36 rad

R: 78° são 1,36 radianos.

c) 450/x = 180/π

180x = 450*π

x= 1413,71/180

x=7,8539 rad

R: 450° são 7,8539 radianos.

d) 9/x = 180/π

180x= 9*π

x=28,27/180

x=0,157 rad

R: 9° correspondem a 0,157 radianos.
