You are in a hot air balloon that is 600 feet above the ground where you can see your friend. If the angle from your line of sight to your friend is 20°, how far is he from the point on the ground below the hot air balloon to the nearest foot?

 tan 20 = opposite side / adjacent side =  6oo/ d              

   d =   600/ tan20o  =  __________ ft
