To solve this problem you must apply the proccedure shown below:
1. You have the following angle given in the problen above:
-230°
2. Then, to find the least positive angle measurement that is coterminal with -230°, you must add 360°, as below:
coterminal angle=-230°+360°
coterminal angle=130°
3. Therefore, as you can see, the answer is: 130°
