Step-by-step explanation:

Given  

An observer standing on the deck of a ship just sees the top of a lighthouse that is 30 m above the sea level. If the height of the observer's eye is...

ANSWER

Given Distance to the horizon d = √h / 0.06735, so h is the height above the sea level .

Now distance of the observer from the light house will be  

  √30 / 0.06735 +  √10 / 0.06735

   21.10531 + 12.185158

    = 33.29

   = 33.3 km
