Anyone? How Do I solve this, I don't understand the solution

anonymous · Answer

I think they are trying to help you find the general solution for any rad $$\theta ^{r}$$

$$\theta ^{o} = \theta ^{r} *  \frac{ 180 }{ \pi  }$$

waheguru · Answer

How Do I find them, I dont understand how?

anonymous · Answer

multiply your radians by 180/pi to convert to degrees. what's not to get?

hartnn · Answer

to convert radians into degrees
just replace pi radians by 180 degrees....thats what they have done ....and then simplified....because pi=180

anonymous · Answer

if you want to know why you can do this
$$\pi=180$$
$$\frac{\pi}{180}=1$$
essentially you're just multiplying by 1

anonymous · Answer

to be clear --
π radians = 180 degrees
π does NOT = 180

The answer is as @petewe said above. Multiply your radians by 180/π to convert to degrees.
