Which of the following represents the measures of all angles coterminal with a negative 220 degrees angle?

Coterminal angles differ by whole rotations of 360°. Adding 360° to −220° gives 140°, so all such angles are 140° + 360n, where n can be any integer. Integers include negative values, which are needed to represent rotations in the opposite direction; therefore, the correct choice is “140 plus 360n, for any integer n.”
