3. The Law of Sin In ANY triangle with angles A,B,C and opposite sides a,b,c the following is true Sin A = Sin B = Sin C a b c

4. Find a 40 10 30 Sin40 = Sin30 a 10 a = 10Sin40 Sin30 a = 12.855 a

5. Find b 50 b 62 Sin50 = Sin62 4 b b = 4Sin62 Sin50 b =4.610 4

6. Find B 54 15 Sin54 = SinB 13 15 SinB = 15sin54 13 B= sin-1(15sin54) 13 B 13 B = 68.984

7. Find B 30 7 Sin30 = SinB 6 7 SinB= 7Sin30 6 B = Sin-1(7Sin30) 6 B B=35.7 6
