For the rotation −1053∘, find the coterminal angle from 0^{\circ} \leq \theta<360^{\circ} , the quadrant, and the reference angle.The coterminal angle is □∘, which lies in Quadrant □, with a reference angle of □∘.
Q. For the rotation −1053∘, find the coterminal angle from 0∘≤θ<360∘, the quadrant, and the reference angle.The coterminal angle is □∘, which lies in Quadrant □, with a reference angle of □∘.
Add 360°: To find the coterminal angle, add or subtract multiples of 360° until the angle is between 0° and 360°.−1053°+360°=−693°
Keep adding 360°: Keep adding 360° until the angle is positive.−693°+360°=−333°
Add 360°: Add 360° again.−333°+360°=27°Now, 27° is between 0° and 360°, so it's the coterminal angle we're looking for.
Identify Quadrant: The coterminal angle 27° lies in Quadrant I because it's between 0° and 90°.
Find Reference Angle: The reference angle is the acute angle formed by the terminal side of the angle and the x-axis. Since 27∘ is already in Quadrant I and is acute, the reference angle is the same as the coterminal angle: 27∘.
