Ex 2) Solve △ ABC if a = 14.3, b = 10.6 and c = 8.4 Divide class into 3 different groups Each group solves the △ in a different order 14.3 10.6 8.4 B C A Group 1 1.m ∠ A (law of cos) 2.m ∠ B 3.m ∠ C law of sines Group 2 1.m ∠ B (law of cos) 2.m ∠ A 3.m ∠ C law of sines Group 3 1.m ∠ C (law of cos) 2.m ∠ A 3.m ∠ B law of sines
