Answer 5

HI!!

Answer 6

hi

Answer 7

the real cube root of \(-2\) sits right on the real axis
the other two divide the circle up in to 3 parts

Answer 8

with the real cube root of two as one of them
of course 3 parts because it is the cubed root
it should be clear from the picture what the angles are

Answer 9

okay, so the angles are 60, 180, and 300?

Answer 10

yeah

Answer 11

although adults use radians, not degrees, but whatever

Answer 12

does that mean it's the first option?

Answer 13

yes
