Answer:
1. 270 x pi/180 = 4.71 rad
2. 135 x pi/180 = 2.36 rad
3. 330 x pi/180 = 5.76 rad
560 degrees = 360 degrees + 200 degrees which is greater than 360 degrees.
For the terminal angle smaller than 360 degrees we have subtract 360 degrees from 560 degrees
560 - 360 = 200 degrees.
The answer is C. 200 degrees.
x^2-2x+1=4 subtract 4 from both sides
x^2-2x-3 factor
(x-3)(x+1) set equal to zero
x=3, -1
