Q. For the rotation 555 -555^{\circ} , find the coterminal angle from 0θ<360 0^{\circ} \leq \theta<360^{\circ} , the quadrant, and the reference angle.\newlineThe coterminal angle is \square^{\circ} , which lies in Quadrant \square, with a reference angle of \square^{\circ} .
  1. Find Coterminal Angle: To find the coterminal angle, add or subtract multiples of 360°360° until the angle is between 0° and 360°360°.\newline555°+360°=195°-555° + 360° = -195°\newline195°+360°=165°-195° + 360° = 165°
  2. Identify Coterminal Angle: Since 165165^\circ is between 00^\circ and 360360^\circ, it is the coterminal angle we're looking for.\newlineThe coterminal angle is 165165^\circ.
  3. Determine Quadrant: To determine the quadrant, check where 165°165° lies.\newline0° < 165° < 90° is Quadrant I\newline90° < 165° < 180° is Quadrant II\newlineSo, 165°165° is in Quadrant II.
  4. Calculate Reference Angle: The reference angle is the acute angle between the terminal side of the given angle and the x-axis.\newlineFor angles in Quadrant II, subtract the angle from 180180^\circ.\newlineReference angle = 180165=15180^\circ - 165^\circ = 15^\circ
