Find the least positive angle measurement that is coterminal with -230 degrees

Answer with explanation:

The two angles having same initial side and terminal side are called Co-terminal angles.Angles Co-terminal with any angle can be found by, adding 360° or 2π to that angle.

Angles that are Co-terminal with (-230°) is equal to = 360° +(-230°)=130°

Other angle ,Co-terminal with (-230°) is equal to = 130°+ 360°=490°

Third angle, Co-terminal with (-230°) is equal to = 490°+ 360°=850°

So,least Positive Co-terminal angle  with (-230°) is equal to = 130°

b is the correct answer
