Example 1

Find sin L, cos L, tan L, sin M, cos M, and tan M. Express each ratio as a fraction and as a decimal to the nearest hundredth.

1. $\ell=15, m=36, n=39$
2. $\ell=12, m=12 \sqrt{3}, n=24$

3. Find $\sin R, \cos R, \tan R, \sin S, \cos S$, and $\tan S$. Express each ratio as a fraction and as a decimal to the nearest hundredth.

4. Find $\sin J, \cos J, \tan J, \sin L, \cos L$, and $\tan L$. Express each ratio as a fraction and as a decimal to the nearest hundredth if necessary.
