Let @ = theta.

sin @ = sqrt(3) / 2

The sine function equals sqrt(3) / 2 at the following angles measured in degrees:
....,-300, 60, 420, 780,1140,....,60 + 360k and
....,-240, 120, 480, 840, 1200,....,120 + 360k where k is an integer.

@ = 60 + 360K and
@ = 120 + 360K

if k = 0 ; @ = 60 degrees ;
