Trigonometry (from Ancient Greek τρίγωνον (trígōnon) 'triangle', and μέτρον (métron) 'measure') is a branch of mathematics concerned with relationships between angles and ratios of lengths. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies. Webreference angle. 9. 2 3S J The angle J is on the positive y-axis.

So, in your case, we have 6π 7 radians, which is the same as 6 7π. Now, if π radians is 180°, all we have to do is change it: 6 7 π = (6 7)180°. Now simply multiply it in whichever method you wish: (6 7)180 = 154.286°.
