Explanation / Answer

Step 1: subtract/add 2 until angle is between 0 and2. Step 2: figure out what quadrant angle is Step 3: In quadrant I, you're done. In quadrants II and IIreference angle is |-|. In quadrant IV referenceangle is 2- 1.) t = -11/13 Step 1: -11/13 + 2 = 15/13 Step 2: 15/13 is in quadrant III Step 3: |15/13-| = 2/13. This is thereference angle 2.) t = 7 Step 1: 7 - 2 Step 2: 7 - 2 is in quadrant I Step 3: 7 - 2 is the reference angle
