3.  Timmy’s cat ran up a tree and is stuck at the top. Timmy asked a firefighter to come help with his ladder.

4.  If the firefighter puts the ladder at a 65° to the ground and the cat is 7 feet up the tree, what length must the ladder be and at what angle is the cat to the ladder? 65° 7 x 

5.  Sin(65°)= 7/x (7)/sin(65°)=x x=7.7 ft  90+65=155 180-155=25°=

6. 7 7.7 65° 25°

7.  The ladder’s length must be 7.7 feet and it must be at a 25° angle with the cat.  And now Timmy knows to watch his kitten while they play outside.
