Harold, the happy concrete guy, got a call on the phone about some concrete he has to pour for an oddly shaped triangular patio. The only information he is given is that the side lengths were $5, 6$, and $8$ meters long.  

1. Calculate the angles for Harold so he can stay happy.

   Hint (a):

   Draw and label a diagram. Then use the Law of Cosines to determine the angle measures.

2. What is the area of the patio that Harold will be forming?

   Hint(b)

   $\text{area}=\frac{1}{2}ab\sin\left(\theta\right)$
