thanks. I already figured it out though. xP

Answer 7

ok great, glad you were able to figure it out

Answer 8

Can you help with this?

120°

Answer 9

one sec while I draw

Answer 10

K

Answer 11

how many angles have I highlighted?

8

Answer 20

so 8*30 = 240 is your answer

Answer 21

why times 30?

Answer 22

and I really don't get this.

(1 point)
72°
108°
36°
288°

Answer 23

because each angle I highlighted is 30 degrees

Answer 24
