1-114.

Draw and label a diagram.

Since no angle measures are given, what formula should be used?

Law of Cosines *a*² = *b*² + *c*² - 2*bc*(cos* A*)

Use the Law of Sines to find another angle.

Draw a segment from angle *C* ⊥ to side *AB*.

Label the intersection point *E*.

Using the sine function, calculate the height, *EC*.

Determine the area of Δ*ABC* by calculating half of the base (8) times the height (*EC*).
