Well in math pie is pi unless your multiplying pi and e but I assume your using pi. First I would convert pi/6 form radians to degrees. It comes out to be. 330 degrees. Now I would subtract 360 to find a co-terminal angle. The angle would be -30 degrees. Then you just plug it in to a calculator and it turns out that the answer is A -1/2.
