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°
