Q. Find an angle θ coterminal to −424∘, where 0∘≤θ<360∘.Answer:
Add 360 degrees: To find an angle coterminal to −424 degrees that is between 0 and 360 degrees, we need to add or subtract multiples of 360 degrees until we get an angle in the desired range. Since −424 degrees is negative, we will add 360 degrees until we are within the range of 0 to 360 degrees.
Add 360 degrees: First, add 360 degrees to −424 degrees to get a new angle.−424 degrees +360 degrees =−64 degreesThis angle is still negative, so we need to add 360 degrees again.
Check range: Add 360 degrees to −64 degrees to get the coterminal angle.−64 degrees +360 degrees =296 degreesThis angle is now within the desired range of 0 to 360 degrees.
Final coterminal angle: Check to ensure that 296 degrees is indeed between 0 and 360 degrees.0 degrees ≤296 degrees < 360 degreesThis is true, so 296 degrees is the coterminal angle we were looking for.
