Find the bisecting line of the acute angle between the lines3x-4y+2=0,-12x+5y-2=0\,

Equation to the given lines are taken as 3x-4y+2=0,12x-5y+2=0\, let this equations be 1 and 2.

Equations to the bisecting lines between given lines are

{\frac  {3x-4y+2}{{\sqrt  {9+16}}}}=\pm {\frac  {12x-5y+2}{{\sqrt  {144+25}}}}\,

39x-52y+26=60x-25y+10or-60x+25y-10\,

21x+27y-16=0\,
