Answer:
let the triangle be ABC
and side BC extended to D
angle BAC = 50° , angle ABC = m ( let suppose )
angle ABD = 120°
now , angle m = 180° - 120° ( straight line theorem )
then angle m = angle ABC = 60°
now in triangle ABC
angle x + angle BAC + angle ABC = 180°
x + 50° + 60° = 180°
x + 110° = 180°
x = 180° - 110° = 70°
