First, it is pi, not pie.
-17*pi/6 = -25/6*pi
To get a reference angle, add multiples of 2*pi.
Two lots of 2*pi gives 11/6pi as the reference angle.
60 degrees each.
sin150 is 0.5 Remember that 150o is 5π/6 radians and the reference angle is π/6 or 30o. sin30 is 0.5
Each piece can have any angular measure provided that the sum of the angles is 360 degrees.
Divide the number of sides into 360 degrees and then subtract your answer from 180 degrees to give you the interior angle. For example a regular hexagon has 6 equal sides and 360 divided by 6 = 60 degrees (the exterior angle) 180 - 60 = 120 degrees (the interior angle)
60 degrees because 360 degrees divided by 6 sides equals 60 degrees
