Q. Find an angle θ coterminal to −253∘, where 0∘≤θ<360∘.Answer:
Add 360 degrees: To find a coterminal angle, we can add or subtract multiples of 360 degrees (a full circle) to the given angle until the result is within the desired range of 0 to 360 degrees.
Find positive coterminal angle: Since −253 degrees is negative, we will add 360 degrees to it to find a positive coterminal angle.−253 degrees + 360 degrees = 107 degrees
Check within range: Now we check if 107 degrees is within the range of 0 to 360 degrees.0 degrees ≤107 degrees < 360 degreesThis is true, so 107 degrees is a coterminal angle to −253 degrees within the specified range.
