Q. Find an angle θ coterminal to −276∘, where 0∘≤θ<360∘.Answer:
Add 360° to −276°: To find an angle coterminal with −276° that is between 0° and 360°, we need to add or subtract multiples of 360° until we get an angle in the desired range. Since −276° is negative, we will add 360° to it.Calculation: −276°+360°=84°
Check if angle is within range: Now we need to check if the new angle, 84∘, is within the range 0^\circ \leq \theta < 360^\circ.Since 84∘ is greater than 0∘ and less than 360∘, it is within the desired range.
