Answer 4

i suppose if you want to put it like that

Answer 5

can u help me with another question

Answer 6

Angle B, where 360degrees < B < 720 degrees, is coterminal with angle A, which has a measure of 100 degrees. The measure of angle B, to the nearest degree, is

Answer 7

its less than and equal to for both signs

Answer 8

one rotation on the unit circle is 360 degrees, so 720 degrees is two rotations

Answer 9

if you want to find an angle coterminal with 100 degrees after 1 rotation, you'd add 360

Answer 10

so an angle of 100º is coterminal with an angle of 460º

Answer 11

1/2
