Answer:

2. quadrant 4

3. quadrant 2

4. quadrant 3

Explanation:

You can refer to the picture.

2. Since
$tan\theta$ less than 0 which means
$tan\theta$ is negative,
$sin\theta$ less than 0 which means
$sin\theta$ is negative.

So, the angle lies in quadrant 4 (Cos quadrant)

3. Since
$tan\theta$ less than 0 which means
$tan\theta$ is negative,
$cos\theta$ less than 0 which means
$cos\theta$ is negative.

So, the angle lies in quadrant 2 (Sin quadrant)

4. Since
$tan\theta$ more than 0 which means
$tan\theta$ is positive,
$sin\theta$ less than 0 which means
$sin\theta$ is negative.

So, the angle lies in quadrant 3 (tan quadrant)
