Kind of confused here

anonymous · Answer

First, is there a picture that goes with this?  Second, have you studied radians before?

anonymous · Answer

No pictures, and yes I have but not very good at it

anonymous · Answer

In a circle, there are 360º and there are 
$$2\pi$$ radians;  so for this problem you can set up the conversion

$$ A \ \textrm{radians} \Big( \frac{360º}{2\pi \ \textrm{radians}} \Big) = Bº$$

anonymous · Answer

Well, there is one problem - they don't give you the num bers they want you to convert....

anonymous · Answer

that's kind of an issue :/

anonymous · Answer

oh sorry for 1a) it's 22.5 degrees

anonymous · Answer

for 2a) it's 22.5 aswell

anonymous · Answer

sure they do, they are giving you the angle in radians, |dw:1383282374554:dw|
