The minimum setback shall be reduced to 40 feet where a horizontal extension the lines created by the nearest exterior vertical surfaces of adjacent buildings would create an angle of not less than 45 degrees.
      (2)   Minimum setbacks between adjacent multiple buildings on sides of multiple- residential buildings shall be 15 feet or a distance equal to half the combined height of the adjacent building faces, whichever is greater.
