Identifying the basic acute angle, \(\alpha \)
On separate diagrams, draw a diagram showing the quadrant which the rotating line \(OA\) lies in for an angle of
- \(515^\circ\)
- \(-195^\circ\)
- \(\frac{8}{3}\pi\)
In each case, clearly indicate the direction of rotation and find the basic acute angle, \(\alpha\).
