Angle BDC is given.
angle ADC= angle BDC+ angle BDA
180 = 96+ angle BDA ( angle ADC being a straight line)
angle BDA= 180-96= 84
We know that sum of three angles of a triangle is 180.
angle ABD + angle BDA + angle DAB = 180
=> 3 angle DAB + 84+ angle DAB =180
=> 4 angle DAB = 180-84=96
=>angle DAB=96÷4=24
=>angle DAB =24
From above, angle ABD =3 angle DAB
=>angle ABD= 3×24=72
I hope it helps you.
