Explicación paso a paso:
Grados a radianes
170°=
[tex]170\times\frac{\pi}{180} = \frac{170}{180}\pi = \frac{17}{18}\pi[/tex]
250°=
[tex]250\times\frac{\pi}{180} = \frac{250}{180}\pi = \frac{25}{18}\pi[/tex]
Radianes a grados
1.3 rad =
[tex]1,3\times\frac{180}{\pi} = \frac{(1,3\times180)}{1\times\pi} = \frac{234}{ \pi}[/tex]
1/5 rad=
[tex]\frac{1}{5}\times\frac{180}{\pi} = \frac{(1\times180)}{5\times\pi} = \frac{180}{5\pi} = \frac{36}{ \pi}[/tex]
