Read the documentation please. It describes exactly that that method returns.

Returns the approximate initial bearing in degrees East of true North when traveling along the shortest path between this location and the given location. The shortest path is defined using the WGS84 ellipsoid. Locations that are (nearly) antipodal may produce meaningless results.

Parameters

dest the destination location

Returns

the initial bearing in degrees
