Question

Qual e o valor de 20 30 em radianos?

Answer 1

Vamos lá...

$x \pi =20 \\ \\ x = \frac{20}{ \pi }= \frac{20}{180}= \frac{1}{9} \\ \\ logo 20^0= \frac{1 \pi }{9} \\ \\ \\ \\ x \pi =30 \\ \\ x = \frac{30}{ \pi }= \frac{30}{180}= \frac{1}{6} \\ \\ logo 30^0= \frac{1 \pi }{6}$

=)

Answer 2

20°
π rad     180
x            20  >> 20π = 180x 

x = 20π/180
x = π/9 rad

30°

π rad   180
x           30 >> 30π= 180x

x= 30π/180
x=π/6  rad
