1. Good afternoon Happy Thursday!
12/4

2. Yesterday
Yesterday we discovered the Law of Sines. Today we will practice using it.

3. Steps 1 Memorize the Law of Sines
2) Use picture given, if no picture sketch one
Label sides and angles appropriately
3) Make sure you have the necessary part of the triangle to use Law of Sines. *
4) Solve for missing piece or pieces asked for.

4. Necessary Parts
Necessary parts of a triangle when using Law of Sines are:
2 angles and one corresponding side. (angle A, angle C and then side a or side c)
2) 2 sides and one corresponding angle. (Side a, Side b and angle A or angle B
So we either need an AAS triangle or a SSA triangle

5. Today
We will mostly deal with AAS triangles today.

6. Example one m<A= 20° m<C=25° c=80.4 Solve the triangle: m<B=

7. Example 2 you try
Triangle JKL 𝑚<𝐽=100° 𝑚<𝑘=30° 𝑘=2 Solve for side j

8. You try some more!
