(3,120degree)

(3,0 degree)I think it is this one??

((-3,0 degree)

2.Which is not a representation of (5,150 degree)

(-5,-30 degree)I think it is this one?

(-5,330 degree)

(5,510 degree)

3.Give 3 representations of (3,240 degree)One has to be in radians

My choices are: (3,600 degrees)

(3,-120 degree degree)

(-3,pi/3)

4.Give 3 representations of (-6,3pi/4)one has to be radians

I gave-(-6,495 degrees)

(-6,-225 degrees)
