Give the angle measure represented by 36.25 rotations counterclockwise

You could say 360(36.25)=13050° but all of the trigonometric relationships will still just obey that angle which is the fractional part because each rotation returns you to the positive x axis.  The resulting angle is just .25(360)=90°.

So 13050° is the total angular rotation and 90° is the relative position with respect to the starting point.

The answer is b: step 2.

(-14+3/2b) - (1+8/2b) = -5 -5/2b(-10+b) + (7b-5) = 8b-15(7/2b-3) - (8+6b) = -5/2b-11(5+2b) + (2b+3/2) = 4b+ 13/2
