  ∠4 = 180° -∠2 = 180° -72°

  ∠4 = 108°

The measure of angle ABD (m∠ABD) is 104°

<h3>Calculating the measure of angles </h3>

From the question, we are to determine the measure of angle ABD

In the diagram,

∠ABC = ∠ABD + ∠DBC

Thus,

m∠ABC = m∠ABD + m∠DBC

From the given information,

m∠ABC = 140°

m∠DBC = 36°

∴ 140° =  m∠ABD + 36°

m∠ABD = 140° - 36°

m∠ABD = 104°

Hence, the measure of angle ABD (m∠ABD) is 104°
