1. Problem Description

The problem asks to convert 2π5\frac{2\pi}{5} radians to degrees.

2. Solution Steps

To convert radians to degrees, we use the following conversion factor:
1 radian=180π degrees1 \text{ radian} = \frac{180}{\pi} \text{ degrees}.
So, to convert 2π5\frac{2\pi}{5} radians to degrees, we multiply by the conversion factor:
2π5 radians=2π5180π degrees\frac{2\pi}{5} \text{ radians} = \frac{2\pi}{5} \cdot \frac{180}{\pi} \text{ degrees}
We can simplify this expression:
2π5180π=21805=3605=72\frac{2\pi}{5} \cdot \frac{180}{\pi} = \frac{2 \cdot 180}{5} = \frac{360}{5} = 72
Therefore, 2π5\frac{2\pi}{5} radians is equal to 7272 degrees.

3. Final Answer

72 degrees
