Answer: The angle is 340°
Step-by-step explanation:
Two angles are coterminal if they have the same terminal side.
For a given angle A, you can find coterminal angles to it by adding 360° or by subtracting 360°.
Then, if we have the angle -20° and we want to find the least positive angle, we need to add 360° (because if we subtracted the result would be a negative number).
Then we have:
-20° + 360° = 340°
Then the smallest positive coterminal angle to -20° is 340°
