Law of Sines

Law of Sines

1.   Solving for a side of a triangle with the Law of Sines (5:57)

   One angle of measure degrees across from a side of length two, another angle measuring degrees.  Sal finds that the side across from the 45 degree angle is approximately 2.83 and the one across from the other (105 degree) angle is approximately 5.86.

2.   Solving for an angle using the law of sines (5:33)
   Distance between two people is 40 , find the angle between one of the people and the kite she is flying, which is 30 away from her.  The angle between the ground near the friend and the kite is 40 degrees.
3.   Find the missing triangle measures using the law of sines.
4.   Proof of the law of sines (6:34)
