7-80.

Consider the triangle below.

1. Solve for $x$ in the diagram.

Once you have determined the measure of the missing angle, use the Law of Sines.

$x \approx 6.4 \text{ units}$

1. What is the area of the triangle?

Draw in a height, which forms two right triangles, then use trigonometry to find the height of the triangle.

$\approx \ 10.1 \text{ square units}$
