Angle of depression (declination) between sailboat observations |
2007-07-18 |
|
From Joyce:
From a cliff 150 ft above a lake, we see a boat sailing directly towards us.
The angle of depression of the boat is seen to be 5 degrees and 7 inches and
11 degrees and 18 inches. Find the distance sailed between observations.
