Identify the anti-clock wise angle.

If the angle $7°{30}^{\text{'}}$ in radians is $\frac{\mathrm{\pi }}{k}$, then find $k$.

If the angle $225°$ in radians is $\frac{5\mathrm{\pi }}{k}$, then find $k$.

Express in terms of a right angle the angle $210°{30}^{\text{'}}{30}^{\text{'}\text{'}}$.

If the angle $330°$ in radians is $\frac{11\mathrm{\pi }}{k}$, then find $k$.

If the angle $36°$ in radians is $\frac{\mathrm{\pi }}{k}$, then find $k$.
