I would convert to degrees first seems to make it easier.

= -468
by adding 360 twice we get the coterminal angle 252
252 is in the 3rd quadrant so 180 is the closest angle on the x-axis
ref angle = 252 - 180 = 72
If necessary convert back to radians...
8,624 rounded to the nearest thousand is 9,000
Hope this helps

It should be the 3rd one but idk for sure. if its not then its the 3rd one
