Have you known the unit circle?
The circle is divided into 4 equal parts such that each part is 90degrees
the first quadrant being at the upper right part of the circle having x and y coordinates positive, the second quadrant at the upper left of the circle having x as negative and y positive, the third quadrant at the bottom left part having both x and y as negative and the fourth quadrant located at the bottom right with x positive and y negative..
From zero degrees located along the positive x axis moving counterclockwise, the angles are positive but when moved clockwise, the reading would be negative.
1. since zero degree is located along the positive x axis and the given angle is positive 85, then we move counterclockwise. 85 is in the first quadrant
2. 3rd quadrant
6. 3rd (note that 360 degrees is 2π)
