The Law of Sines - Lesson+Practice

The [i]law of sines[/i] (or sine rule) relates the lengths of the sides of a triangle with the sines of its angles.[br][br]The apple below allows you to discover this useful law ([i]Theorem[/i]), learn how it is obtained ([i]Proof[/i]) and interact with a dynamic triangle ([i]Explore![/i]) to become familiar with this concept.
Solving a triangle means finding missing sides and angles - Let's solve one.
About the triangle in the app above, we know that [math]a=24[/math], [math]\beta=60°[/math] and [math]\gamma=45°[/math]. [br]Solve the triangle.
To be or not to be....
Use the law of sines to show if a triangle with:[br][math]a=18[/math], [math]b=36[/math] and [math]\alpha=45°[/math] does exist or not.[br][br]Explain you reasoning below.
