\

a). \ \

\

The angle $\"\"$ = $\"\"$ . \ \

\

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

\

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

\

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

\

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

\

The angle is $\"\"$ . \ \

\

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

\

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

\

b). \ \

\

The angle $\"\"$ = $\"\"$ . \ \

\

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

\

So it is in quadrant IV. \ \

$\"\"$ \ \

\

Therefore, \ \

\

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

\

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