9-44.

Change the angle measurements below from radians to degrees or from degrees to radians.

1. $144°$

$\frac{144°}{180°} = \frac{x}{\pi}$

$\frac{144°}{180°} = \frac{x}{\pi} \; \text{so} \; \frac{4}{5}\pi = x$

1. $300°$

$270°+30°$

$\frac{3}{2} \pi + \frac{1}{6}\pi = \frac{10}{6}\pi = \frac{5}{3}\pi$

1. $\frac { 5 \pi } { 9 }$

$\pi=180°$

$\frac{5 \cdot 180°}{9} = 5 \cdot 20°= 100°$

1. $\frac { 17 \pi } { 12 }$

Follow a process like (c) above.

1. $\frac { 19 \pi } { 2 }$

Follow a process like (c) above.

1. $220°$

Follow a process like (c) above.
