You are standing on a beach next to the ocean. Assuming you are 6 feet tall and the earth's diameter is 8000 miles how far is the horizon? (Remember, the line from your eye to the horizon makes a tangent to earth at the horizon. Also remember, the earth is round and a tangent forms a right angle to a radius of a circle)​
