If the Greenwich Hour Angle (GHA) of the sun is 173deg the Local Hour Angle (LHA) is 358deg ... What is the longitude?

To find the longitude, you can use the formula: Longitude = GHA - LHA. In this case, GHA is 173° and LHA is 358°. So, Longitude = 173° - 358° = -185°. Since longitude values range from -180° to 180°, you can convert -185° to 175° (by adding 360°), indicating that the location is at 175° E longitude.
