**Converting Radians to Degrees** To convert an angle from radians to degrees, use the following formula: \[ \text{Degrees} = \text{Radians} \times \frac{180}{\pi} \] Let's apply this formula to the given problem: ### Problem Convert the angle in radians to degrees. Given: \[ \frac{14\pi}{9} \text{ radians} \] ### Solution 1. **Multiply by the Conversion Factor:** \[ \text{Degrees} = \frac{14\pi}{9} \times \frac{180}{\pi} \] 2. **Simplify the Expression:** \[ \text{Degrees} = \frac{14 \times 180}{9} \] 3. **Calculate the Result:** \[ \text{Degrees} = \frac{2520}{9} = 280^\circ \] Therefore, \(\frac{14\pi}{9}\) radians is equal to \(280^\circ\). ### Explanation - **Conversion Factor**: We use \(\frac{180}{\pi}\) because \(180^\circ\) is equivalent to \(\pi\) radians. - **Simplification**: \(\pi\) in the numerator and denominator cancels out, simplifying calculation. - **Calculation**: Perform arithmetic to find the degree measure. This approach helps in converting any radian measurement into degrees effortlessly.
