(a).

The angle is $\"\"$ .

The angle $\"\"$ is negative angle.So, negative angles are generated by clock wise rotation.

$\"\"$ to $\"\"$ is quadrant IV.

$\"\"$ to $\"\"$ is quadrant III.

$\"\"$ to $\"\"$ is quadrant II.

$\"\"$ to $\"\"$ is quadrant I.

The angle $\"\"$ is between $\"\"$ and $\"\"$ .

The angle is in Quadrant II. $\"\"$

(b).

The angle is $\"\"$ .

The angle $\"\"$ is between $\"\"$ and $\"\"$ .

So it is in quadrant IV. $\"\"$

(a) The angle $\"\"$ is in Quadrant II.

(b) The angle $\"\"$ is in Quadrant IV.
