Explicação passo-a-passo:
Transformar os graus abaixo em Radianos :
a) 380 ° (ok)
TT rad = 180
X = 380
TT rad/x = 180/380 (:10)/(:10)
TT rad/x = 18/38 (:2)/(:2)
TT rad/x = 9/19
19 TT rad = 9.x
9.x = 19 TT rad
x = 19/9 TT rad
R.: x = 19/9 TT rad
_______________
b) 410 ° (ok)
TT rad = 180
x = 410
TT rad/x = 180/410
TT rad/x = 18/41
41TT rad = 18.x
41 TT rad/18 = x
x = 41/18 TT rad
R.: x = 41/18 TT rad
________________
c) 260° (ok)
TT rad = 180°
x = 260°
TT rad/x = 180/260
TT rad/x = 18/26 (:2)/(:2)
TT rad/x = 9/13
13 TT rad = 9.x
9x = 13 TT rad
x = 13/9 TT rad
R.: x = 13/9 TT rad
_______________
d) 128 °
TT rad = 180
x = 128
TT rad/x = 180/128 (:4)/(:4)
TT rad/x = 45/32
32 TT rad = 45.x
45.x = 32 TT rad
x = 32/45 TT rad
R.: x = 32/45 TT rad

e)490°
TT rad = 180°
X = 490°
TT rad/x = 180/490
TT rad/x = 18/49
49 TT rad = 18.x
18.x = 49 TT rad
x = 49/18 TT rad
R.: x = 49/18 TT rad
