Q. Find an angle θ coterminal to 938∘, where 0∘≤θ<360∘.Answer:
Find Co-terminal Angle: To find an angle θ coterminal to 938 degrees where 0 degrees \leq \theta < 360 degrees, we need to find the equivalent angle within one full circle (0 to 360 degrees). We do this by subtracting or adding multiples of 360 degrees from the given angle until the result is within the desired range.Calculation: 938−360×2=938−720=218 degrees.
Calculate Equivalent Angle: We check if the angle 218 degrees is within the range 0 degrees \leq \theta < 360 degrees.Since 218 is greater than 0 and less than 360, it is within the desired range.
