To wit - suppose the Altitude to be 40[[degree symbol]] - 40[[feet symbol]] ^[[(which includes the 12[[feet symbol]])] - the reading by the [[underlined]] reverse [[/underlined]] line would be 49[[degree symbol]] = 2-, thus obviating the necessity of taking the usual reading (say ^[[as]] the given instance [[strikethrough]] ) [[/strikethrough]] 40[[degree symbol]] - 40[[feet symbol]] & subtracting it from 90[[degree symbol]], which would give the same result.
