120 degrees


The total angle that is available around the point is 360 degrees (a circle). If three friends are moving away at equal angles, then they each "occupy" a third of the total circle.

#360/3 = 120# degrees

We can't tell exactly which direction on an XY plane each person is going, but they are 120 degrees apart.
