Q. Find the measure of a negative angle coterminal with 170∘170^\circ. \newline____∘^\circ
  1. Subtract 360360°: To find a negative angle coterminal with 170°170°, subtract 360°360° from 170°170° because coterminal angles are separated by full rotations, which are 360°360°.\newlineCalculation: 170°−360°=−190°170° - 360° = -190°
  2. Check result and confirmation: Check if the result is a negative angle and if it's coterminal with 170°170°.\newline−190°+360°=170°-190° + 360° = 170°, which confirms that −190°-190° is coterminal with 170°170°.
