Question

Transformar o grau dos radianos e dps obter as medidas

Answer 1

Resposta:

a)

180 ---------------pi

200----------------x

180x = 200*pi

x =200*pi/180 =10/9 pi rad

b)

180 --------pi

x-----------pi/6

180*pi/6=x*pi

x=180/6=30º

c)

5pi/4 =5*180/4=225º

7pi/6=7*180/6=7*30=210º

pi/2=180/2=90º

30----------x

180---------pi  ==> x= 30pi/180=pi/6  rad

60----------x

180---------pi  ==> 60pi/180=pi/3  rad

120----------x

180---------pi  ==> 120pi/180=2pi/3  rad

150----------x

180---------pi  ==> 150pi/180=5pi/6  rad

210----------x

180---------pi  ==> 210pi/180=7pi/6 rad

240----------x

180---------pi  ==> 240pi/180=4pi/3   rad
