  2. Used to solve triangles with SAS and SSS: SSS: Find the largest angle first with the Law of Cosines, then find the next largest angle with the Law of Sines. SAS: Find the 3rd side with the Law of Cosines, then use the Law of Sines to solve for one of the smaller angles. Law of Cosines – SAS and SSS

  3. Ex 1: Find the remaining sides and angles B * Always find the largest angle first and work down from there. 14 8 C A 19

  4. Ex 2: b=15, A=115°, c=10 Find the missing angles and sides

  5. Ex 3. In a baseball game, a batter hits the ball to center field. The center fielder then throws the ball to third base . The distance from the center fielder to home plate is 240 feet. The distance between the bases is 60 feet. How far did the center fielder throw the ball?
