9.6 Apply the Law of Cosines In which cases can the law of cosines be used to solve a triangle? What is Heron’s Area Formula? What is the semiperimeter?
Section 5-8 The Law of Cosines. A b c C a B Solve ∆ABC if A= 120⁰, b=9, c=5.
EXAMPLE 1 Solve a triangle for the SAS case Solve ABC with a = 11, c = 14, and B = 34°. SOLUTION Use the law of cosines to find side length b. b 2 = a.

9.5 Apply the Law of Sines day 3 How do you use the law of sines to find the area of a triangle?
You have used coordinate geometry to find the midpoint of a line segment and to find the distance between two points. Coordinate geometry can also be used.
