Q. Find an angle θ coterminal to 913∘, where 0∘≤θ<360∘.Answer:
Understand coterminal angles: Understand what a coterminal angle is.Coterminal angles are angles that share the same initial and terminal sides but may differ by any number of full rotations (360∘). To find a coterminal angle to 913∘ that lies between 0∘ and 360∘, we need to subtract or add multiples of 360∘ until the angle falls within the desired range.
Subtract multiples of 360°: Subtract multiples of 360° from 913° until the result is between 0° and 360°.913°−360°=553°553° is still greater than 360°, so we subtract 360° again.553°−360°=193°193° is still greater than 360°, so we subtract 360° one more time.0°1Since we are looking for a positive angle, we add 360° to 0°3.0°4
