So my question is: An angle is 100 degrees. Equivalent to the correct radian. To go about doing this question you have to first convert degrees into radians.To do this is you can make a little converting chart. You put 100 degrees at the top left side then diagnol to it you put 180 degrees, and at the right top corner you put pi. You put 180 in the bottom because one pi is only 180 degrees. Once you have this all written out the degrees will cancel out and then you times the 100 to pi and put it over 180. Then you have to reduce the fraction. So, the answer would be 5pi over 9 radians.
