Positive angles located in the fourth quadrant may be described

1. 0≤ф≤90
2. 180≤ф≤270
3. 90≤ф≤180
4. 270≤ф≤360

Positive angles located in the fourth quadrant may be described as 270≤Ф≤360 .

The option is

4. 270≤Ф≤360

Step-by-step explanation:

When the terminal arm of an angle starts from the x-axis in the anticlockwise direction then the angles are always positive angles.

For Example.

Quadrant I    - 0 to 90°

Quadrant II   - 90° to 180°

Quadrant III  - 180° to 270°

Quadrant IV - 270° to 360° ( 4. 270≤Ф≤360  )

Hence,Positive angles located in the fourth quadrant may be described as 270≤Ф≤360 .

When the terminal arm of an angle starts from the x-axis in the clockwise direction than the angles are negative angles.

Quadrant IV  -          0° to -90°

Quadrant III   -      - 90° to -180°

Quadrant II    -      -180° to -270°

Quadrant I     -      -270° to -360°

i really dont know

but there’s no any figure there!
