which choice is it?

C. or D.

Step-by-step explanation:

I forgot this but, if its the closed circle that represent equal or greater,  its D. If not, its C.

If its the open circle that represent equal or greater,  its C. If not, its D.

I didn't get to finish this unit last year cause of the schools closing.

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
