Q. Find an angle θ coterminal to 698∘, where 0∘≤θ<360∘.Answer:
Subtract 360°: To find an angle coterminal with 698° that lies between 0° and 360°, we need to subtract or add multiples of 360° until the angle is within the desired range.First, let's subtract 360° from 698° to see if we get an angle in the required range.698°−360°=338°
Check if within range: Since 338∘ is less than 360∘ and greater than or equal to 0∘, it is within the desired range. Therefore, 338∘ is coterminal with 698∘ and satisfies the condition 0^\circ \leq \theta < 360^\circ.
