Q. Find the measure of a negative angle coterminal with 240∘240^\circ. \newline____∘^\circ
  1. Subtract 360360°: To find a negative coterminal angle, subtract 360°360° from the given angle until the result is negative.\newlineCalculation: 240°−360°=−120°240° - 360° = -120°.
  2. Check range: Check if the result is within the range of a full circle (−360∘-360^\circ to 0∘0^\circ).\newline−120∘-120^\circ is within this range.
