Answer

Final Answer: The reference angle for a rotation of 249 degrees is 69∘

Steps

Step 1 ：The given angle is 249 degrees.

Step 2 ：Since 249 degrees is in the third quadrant (between 180 and 270 degrees), we can find the reference angle by subtracting 180 from 249.

Step 3 ：Using the formula for the reference angle in the third quadrant, angle−180, we substitute 249 for the angle.

Step 4 ：reference_angle=249−180

Step 5 ：reference_angle=69

Step 6 ：Final Answer: The reference angle for a rotation of 249 degrees is 69∘
