A man standing on the deck of a ship is flying a kite. The ship deck is 30 feet above the water. The kite string is 75 feet long, and the kite flying at an angle of elevation of 60 degrees. How high above the water is the kite?

  1. sintheta = opposite side / hypotenuse
    sin(60)= (height the kite is above the boat)/ 75
    75xsin60 = height of kite above boat
    64.95 feet = height of kite above boat
    Now you need to add the height of the boat deck from the water to your 64.95 to get the height of the kite above the water : )

  2. h = 30 + 75*sin60 = 94.95 Ft. above water.
