State the quadrant in which the angle 8π/5 lie?
- 1st quadrant
- 4th quadrant
- 2nd quadrant
- None of these
Explanation
To determine the quadrant, let's convert the angle to degrees:
8π/5 radians = (8 * 180°) / 5
= 288°
Since 288° lies between 270° and 360° (or -90° and 0° if considering the unit circle in a different manner), it falls in the:
4th quadrant
