STEP 1

What is this asking? We need to find an angle between 00^\circ and 360360^\circ that's essentially the same rotation as 297-297^\circ, figure out which quadrant it's in, and find the smallest angle it makes with the x-axis. Watch out! Negative angles rotate clockwise, and we need a positive coterminal angle!
Also, the reference angle is always positive and less than or equal to 9090^\circ.

STEP 2

1. Find the Coterminal Angle
2. Determine the Quadrant
3. Calculate the Reference Angle

STEP 3

Alright, so we're given this angle of 297-297^\circ.
Since it's negative, it means we're rotating **clockwise** from the positive x-axis.
We want to find an angle between 00^\circ and 360360^\circ that represents the same rotation, but going **counter-clockwise**!

STEP 4

To do this, we can add **full rotations** to our original angle until we land in the desired range.
A full rotation is 360360^\circ, so let's add 360360^\circ to 297-297^\circ:
297+360-297^\circ + 360^\circ

STEP 5

This gives us:
297+360=63-297^\circ + 360^\circ = 63^\circSince 6363^\circ is between 00^\circ and 360360^\circ, this is our **coterminal angle**!

STEP 6

Now, let's see where this 6363^\circ angle hangs out.
Remember: * **Quadrant I:** 00^\circ to 9090^\circ * **Quadrant II:** 9090^\circ to 180180^\circ * **Quadrant III:** 180180^\circ to 270270^\circ * **Quadrant IV:** 270270^\circ to 360360^\circ

STEP 7

Since 6363^\circ is between 00^\circ and 9090^\circ, our coterminal angle is chilling in **Quadrant I**!

STEP 8

The **reference angle** is the smallest angle our coterminal angle makes with the x-axis.
Since we're in Quadrant I, the reference angle is simply the coterminal angle itself!

STEP 9

Therefore, the reference angle is 6363^\circ.

STEP 10

The coterminal angle is 6363^\circ, which lies in Quadrant I.
The reference angle is 6363^\circ.
