units long. In terms of a, b, and C, find the third side of the triangle defined by this SAS description. You have done numerical versions of this question. Start by finding the length

of the altitude drawn to side b, as well as the length of the perpendicular projection of side

a onto side b. The resulting formula is known as the Law of Cosines.

3. What is the area of the triangle defined by a, b, and C?

Then, area= sqrt((s-a)(s-b)(s-c)s)

where s is 1/2 the perimeter. Perimeter then is a+b+thirdside.
