Q. Find an angle θ coterminal to −147∘, where 0∘≤θ<360∘.Answer:
Add 360 degrees: To find an angle coterminal to −147 degrees that is between 0 degrees and 360 degrees, we need to add or subtract multiples of 360 degrees until we get an angle in the desired range. Since −147 degrees is negative, we will add 360 degrees to it.Calculation: −147 degrees + 360 degrees = 213 degrees
Check within range: Now we need to check if the resulting angle, 213 degrees, is within the range of 0 degrees to 360 degrees.Since 213 degrees is greater than 0 degrees and less than 360 degrees, it is within the desired range.
