1. $a=18\text{ft},B=54\xb0$, $C=43\xb0$

2. $b=8\text{m}$, $c=5\text{m}$, $C=36\xb0$

3. $a=16.1\text{in}.$, $b=9.8\text{in}.$, $c=11.2\text{in}$.

4. Find the area of $\text{\Delta}ABC$ if $C=106.4\xb0$, $a=7\text{cm}$, and $b=13\text{cm}$.

5. Distance Across a Lake. Points A and B are on opposite sides of a lake. Point C is 52 m from A. The measure of $\angle BAC$ is determined to be $108\xb0$, and the measure of $\angle ACB$ is determined to be $44\xb0$. What is the distance from A to B?
