  2. first use the formula 180/pi to go from radians to degrees, simplified you get 197.6704393, now multiply the decimal by 60 (because there are 60 minutes in an hour, get it??)and you get 40.226358, to the nearest minute its 40 so all together 197 degrees, 40 minutes. is studying for the Algebra2 trigonometry regents ruining any one elses life?!?!
