Answer

-π/9 radians is -20 degrees, and 2π/5 radians is 72 degrees.

Solution

To convert from radians to degrees, you multiply the radian measure by 180/π. 1. For the angle -π/9 radians:   (-π/9) × (180/π) = -180/9 = -20 degrees.   So, -π/9 radians is equivalent to -20°. 2. For the angle 2π/5 radians:   (2π/5) × (180/π) = 360/5 = 72 degrees.   So, 2π/5 radians is equivalent to 72°. Both conversions are correct.

Did you know that angles measured in radians come from a relationship with circles? Specifically, one full circle (360 degrees) is equal to \( 2\pi \) radians! So, when you're converting radians to degrees, simply multiply by \( \frac{180}{\pi} \). This means an angle of \( -\frac{\pi}{9} \) radians is actually about -20 degrees, wrapping backward around the circle. Converting \( \frac{2 \pi}{5} \) radians to degrees involves the same formula. Multiplying \( \frac{2 \pi}{5} \) by \( \frac{180}{\pi} \) gives you 72 degrees, meaning this angle opens up an engaging path of interpretation for navigation or physics, where angular measurements are pivotal in fostering various real-world applications such as wave patterns and rotational motion!
