  • Tan30=3/x x= 3/tan30 x=5 ft
  • Scared of the fish, Carrie decided to get out of the water. But unfortunately she spotted something else scary waiting outside of the water. A lizard, 6 feet away from her. Using cosine, she was able to find the angle of elevation.

  • Turning to the left Carrie saw a bigger problem, an alligator. Knowing her angle of elevation was 45, and that it was 5 feet from the water, Carrie used sin to find how far from her it was.
