Question 1769Navigation General

The correct answer is C) 144°45'E. The geographic longitude of a body can be determined from its Greenwich Hour Angle (GHA). The GHA is the angular distance of the body measured westward along the celestial equator from the Greenwich meridian to the hour circle passing through the body. When the GHA is 215°15', the longitude of the body is 144°45'E, as the longitude is 360° minus the GHA. The other options are incorrect because 35°15'E is not the correct longitude, 144°45'W is the longitude in the western hemisphere, and 35°15'W is not the correct longitude for the given GHA.
