    Angle 1 = z and angle 2 = x x=z ( given )------------1 x and z are the two interior opposite angles Angle 1+ angle 2 = 115. x+z = 115 (exterior angle sum property) z+z ( from 1) =115 2z = 115 z =115÷2 z=57.5. x=z=57.5 degrees .

    Exterior angle= 115 Let any triangle with angle X Y and Z X and Y angles are equal Exterior angle + Z = 180 by linear pair Z=65 X+Y+Z=180. Angle sum property X +X +65=180 2X=180-65 X= 115/2 X=57.5=Y Hope it helps you ??
