The second direction you could give your friend is azimuth, which is measured from 0 to 360 degrees along the horizon. Face north and you are looking at azimuth 0 degrees. Turn one quarter of the way to your right, facing east and you are looking at 90 degrees azimuth. Facing south is 180, and West is at 270. Again you can estimate the approximate number of degrees from North to locate the object in terms of azimuth.
