1-98.

Make a chart like the one below. It helps you quickly 'see' what needs to be figured out as well as helping you quickly find a strategy.

Determine the measure of angle *G* first. Then use the Law of Sines to calculate the missing side lengths.

Draw a height from vertex *G* ⊥ to side *OD*.

Using your calculation for side *o* and the sine function for angle *D*, find the height. Then use the area formula for a triangle.
