Find the reference angle theta Theta 220 degree Sketch thet
Find the reference angle theta\'. Theta = -220 degree Sketch theta and theta \' in standard position.
Solution
A reference angle is an angle formed by the x axis and the terminal side. For any given angle we need to see the angle formed by its terminal side with axis to find the reference angle
theta\' = 40 deg in Q-II
