Answer:
Quadrant II
Step-by-step explanation:
We can convert 
radians to degrees by multiplying by 
to get 
.
means we are rotating 
clockwise, so you would end up in Quadrant II.
15x would be the vertical angle of 16x -8 and since vertical angles are equal, then 15x = 16x -8.
15x = 16x -8
x = 8 and so the angle 15x = 15 * 8
which equals 120 degrees.
