Find the least positive angle measurement that is coterminal with -20degrees

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°
