### Question:
SphericalMercatorProjection { public static double xToLongitude(double x) { return Math.toDegrees(x / EARTH_RADIUS); }  static double yToLatitude(double y); static double xToLongitude(double x); static double latitudeToY(double latitude); static double longitudeToX(double longitude); static Location ecefToLocation(double[] ecef); static double[] ecefToGeodetic(double[] ecef); static double[] locationToEcef(Location location); static double[] geodeticToEcef(double[] geodetic); static final double EARTH_RADIUS; }### Answer:
@Test public void xToLongitude() { double actualLongitude = SphericalMercatorProjection.xToLongitude(1492232.6533872557); assertEquals(LocationTest.BERLIN.getLongitude(), actualLongitude, 0.00001); }
