IN ∆ADB
AD = AB
Thus ∆ABC is an Isoceles Triangle
So ,
Angle ADB = Angle ABD ( Isoceles Triangle property)
angle A + angle ABD + angle ADB = 180°
130° + 2( angle ABD ) = 180°
angle ABD = (180 - 130)/2
angle ABD = 25°
angle ABD = angle ADB = 25°
angle ADB = angle DBC (alternate interior angles)
x = 25°
