Q. Find the measure of a negative angle coterminal with 270∘270^\circ. \newline____∘^\circ
  1. Subtract 360360°: To find a negative angle coterminal with 270°270°, subtract 360°360° from 270°270° because coterminal angles are separated by full rotations, which are 360°360°.\newlineCalculation: 270°−360°=−90°270° - 360° = -90°.
  2. Check Negative Rotation: Check if −90°-90° is within the range of a full rotation (360°360°) in the negative direction.\newlineCalculation: −90°-90° is within one full negative rotation since it's greater than −360°-360°.
