Convert the angles to degrees. Remember there are 2pi radians in a circle, and a circle has 360 degrees, so conversion factor is 180degrees/pi. Then you can easily approximate the reference angle. Remember you make the reference angle from the positive x-axis and the reference angle will be the angle between the terminal side and the nearest x-axis (either positive side or negative side of the x-axis).
1)1.4 * \frac{180degrees}{pi} = 80.214 degrees
2)-1.4 \pi * \frac{180degrees}{ \pi } = -252 degrees

The answer is 7. You can solve it by going through all the answers and testing the math. 7 x 15$ = 105 so add that to 3 x 25 = 75 and it proves it equals 180$.
