Final answer:
To find the angle that is not coterminal with the other three angles (-610°, 370°, -250°, 110°), we need to convert them all to the smallest positive angles possible. -610° can be converted to 750°, -250° can be converted to 110°. Therefore, the angle that is not coterminal with the other three angles is 110°.
Step-by-step explanation:
Two angles are coterminal if they have the same initial side and terminal side.
To find the angle that is not coterminal with the other three angles (-610°, 370°, -250°, 110°), we need to convert them all to the smallest positive angles possible.
-610° can be converted to 750° (since it is 360° less than 360°).
370° is already a positive angle.
-250° can be converted to 110° (since it is 360° less than 360°).
Therefore, the angle that is not coterminal with the other three angles is 110°.
