  • Mikey's dad cut two branches off of a tree in their backyard. The shorter branch is 2 meters and the other is 50 degrees. What is the length of the hypotenuse?
  • cos 50 = 2 x x= 2 cos50=3.1 m
  • Mikey's dad knocked an egg out of its nest. It made Mikey sad. He thought a bird was inside.
  • The egg drops 30 feet from the tree making a 22 degree angle with the ground. Determine how tall the tree is .
