Hellas Planitia includes the word "planitia" which is the latin word for "plain" in its name.
The name would seem to indicate thats Hellas Planitia is a low lying plain, yet it is clearly a crater, and a very large one at that.
The most probable reason for this discrepancy in its name is because:
a. It is a simple naming error that for some reason has so far escaped correction.
b. There is a disagreement among astronomers about the true nature of Hellas Planitia.
c. Its true nature was not apparent over 100 years ago when it was observed using ground based telescopes.
d. Astronomers really know its true nature and misconceptions among the public among the public are not of great concern to them.

Based on this reading and some information about the sea floor and tides in the area where The Howler was thought to have sunk, you suggest that the team start by taking the search boat 65 meters due east of shore. At this distance the angle of depression between the shore and the hypothetical location of The Howler and its treasure should be about. The search boat will be at the vertex of a angle between the shore and the treasure below. Use this information and what you know about solving triangles using trigonometric functions to explore the questions below. What is the straight-line distance between the treasure and the shore?
