Q. Find an angle θ coterminal to 1119∘, where 0∘≤θ<360∘.Answer:
Divide and Calculate Rotations: To find an angle coterminal to 1119∘ that is between 0∘ and 360∘, we need to subtract or add multiples of 360∘ until we get an angle in the desired range. This is because adding or subtracting full rotations (360∘) does not change the terminal side of the angle.
Subtract Full Rotations: First, we calculate how many full 360° rotations are in 1119° by dividing 1119 by 360. 1119÷360=3.1083...The whole number part of the quotient (3) represents the full rotations.
Find Coterminal Angle: Next, we subtract the full rotations from the original angle to find the coterminal angle within the range of 0∘ to 360∘. 1119∘−(3×360∘)=1119∘−1080∘=39∘
Final Coterminal Angle: The angle 39° is between 0° and 360°, so it is the coterminal angle to 1119° that we were looking for.
