1 Class Work Let’s start with some review!! 1.Solve for x. x 7 42 

2 Trig – Section 6 Law of Sines Objectives: To understand how to use the Law of Sines to solve any triangle.

3 Law of Sines The Law of Sines says that in any triangle the lengths of the sides are proportional to the sines of the corresponding angles. A B C a b c

4 Ex 1. Solve the triangle when given ASA. 30  A B C a b 100 40 

5 Ex 2. Solve the triangle (AAS)

6 Class Work 5. Solve for x. Round answers to nearest tenth.

7 6. Solve for x. Round answers to nearest tenth.

8 You can also use the Law of Sines for two sides and an angle (SSA). Ex 3. Solve  ABC if m  A = 80 , a = 100 and b = 10

9 Ex 4. Solve  ABC if m  A = 41 , a = 40 and b = 89.

10 Class Work 7. Solve  ABC if m  A = 80 , a = 6.5 and b = 3.4 8. Solve  ABC if m  A = 80 , a = 10 and b = 100

11 Class Work Practice Worksheet (odds)
