Section 5-6

1. Section 5-6 The Law of Sines

2. The Law of Sinescan be used to solve triangles that are not right triangles. A b c C a B a = b = c sin A sin B sin C

3. Solve ∆ABC if A=33°, B=105°, and b =37.9

5. Solve ∆LMN if L=29°, M=112°, and l =22 M L N

6. Solve ∆LMN if L=29°, M=112°, and l =22 M 112° n 22 29° L m N m sin 29 = 22 sin 112 m= 42.1 Still need values for N and n

7. N= 39° n= 28.6

8. Solve ∆ABC if A=41°, B=49°, and a =6.5 A c b B a C

9. Solve ∆ABC if A=41°, B=49°, and a =6.5 A 41° c b 49° B 6.5 C C=90° b=7.5 c=9.9
