With your table discuss CAH.

12. Whiteboard Activity
For each triangle, first determine which side lengths have been labeled with relation to the given angle: opposite, adjacent or hypotenuse.
Determine if the problem is a simple trig function (sin/cos/tan)
Then, set up an equation using the appropriate ratio.
YOU DO NOT NEED TO SOLVE FOR X!!!

21. Rules of the game Answer the question as a group on the whiteboard
Every question = new person writes on board
Wait for countdown then hold up answer
Correct = Shot
Basket = Erase one X from another team
Once you lose all your X’s you will become a ZOMBIE! Meaning you can only erase other team members X’s.
