Angles coterminal with 130° differ from it by a multiple of 360°.
490° − 130° = 360° → coterminal
−230° − 130° = −360° → coterminal
50°, 330°, and 430° are not (their differences from 130° are −80°, 200°, and 300°, respectively).
So: 490° and −230°.
490° − 130° = 360° → coterminal
−230° − 130° = −360° → coterminal
50°, 330°, and 430° are not (their differences from 130° are −80°, 200°, and 300°, respectively).
So: 490° and −230°.
