Q. Find an angle θ coterminal to 902∘, where 0∘≤θ<360∘.Answer:
Understand coterminal angles: Understand what a coterminal angle is.A coterminal angle to a given angle is an angle that differs from the given angle by a multiple of 360°. This is because adding or subtracting 360° from an angle does not change its position in the standard position on a coordinate plane.
Calculate coterminal angle: Calculate the coterminal angle.Since 902∘ is more than 360∘, we can subtract 360∘ multiples from it until we get an angle that is between 0∘ and 360∘. We start by subtracting 360∘ once: 902∘−360∘=542∘. This is still greater than 360∘, so we subtract 360∘ again: 542∘−360∘=182∘. This is still greater than 360∘, so we subtract 360∘ one more time: 360∘2. Since we are looking for a positive angle, we add 360∘ to get a positive coterminal angle: 360∘4.
