1 radian=180º/∏ or 180/3.14159=57.295828º
1) 3.2 radians
(3.2)(57.295828)=183.34665º
using only 0.34665º
(0.34665)(60)=20.799'
(0.34665-20/60)(3600)=(0.34665-0.33333)(3600)
(0.01332)(3600)=47.952" or 48"
183º 20' 48"
4) 6 radians
6(180/3.14159)=6(57.295828)=343.77497º
using only 0.77497º
(0.77497)(60)=46.4982'
(0.77497-[46/60])(3600)=(0.77497-0.76666)(3600)
(0.00831)(3600)=29.916" or 30"
343º 46' 30"
