Convert the following radian measures to degrees: i) (7pi/12)c ii) (-5pi/3)c iii) 5c

$$
\left(\frac{7\pi}{12}\right)^c = \left(\frac{7\pi}{12} \times \frac{180}{\pi}\right)^\circ
$$

$$
= \left(\frac{7 \times 180}{12}\right)^\circ
$$
$$
= (7 \times 15)^\circ
$$
$$
= \boxed{\text{}105^\circ\text{}}
$$

$$
\left(-\frac{5\pi}{3}\right)^c = \left(-\frac{5\pi}{3} \times \frac{180}{\pi}\right)^\circ
$$

$$
= \left(-\frac{5 \times 180}{3}\right)^\circ
$$
$$
= (-5 \times 60)^\circ
$$
$$
= \boxed{\text{} -300^\circ\text{}}
$$

$$
5^c = \left(5 \times \frac{180}{\pi}\right)^\circ
$$

$$
= \left(\frac{900}{\pi}\right)^\circ
$$

$$
= \left(\frac{900}{3.14159}\right)^\circ \approx 286.48^\circ
$$
$$
= \boxed{\text{} \left(\frac{900}{\pi}\right)^\circ \approx 286.48^\circ\text{}}
$$

$$
\left(\frac{11\pi}{18}\right)^c = \left(\frac{11\pi}{18} \times \frac{180}{\pi}\right)^\circ
$$

$$
= \left(\frac{11 \times 180}{18}\right)^\circ
$$
$$
= (11 \times 10)^\circ
$$
$$
= \boxed{\text{}110^\circ\text{}}
$$

$$
\left(-\frac{1}{4}\right)^c = \left(-\frac{1}{4} \times \frac{180}{\pi}\right)^\circ
$$

$$
= \left(-\frac{180}{4\pi}\right)^\circ
$$
$$
= \left(-\frac{45}{\pi}\right)^\circ
$$

$$
= \left(-\frac{45}{3.14159}\right)^\circ \approx -14.32^\circ
$$
$$
= \boxed{\text{} \left(-\frac{45}{\pi}\right)^\circ \approx -14.32^\circ\text{}}
$$
