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

its less than and equal to for both signs

one rotation on the unit circle is 360 degrees, so 720 degrees is two rotations
anonymous
  • anonymous
if you want to find an angle coterminal with 100 degrees after 1 rotation, you'd add 360

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

1/2
