Given that AB = AD and ∠ABC - ∠ACB = 32°, how can I find ∠DBC?

Question

Looked through many postulates and theorems but none seemed to help, could anyone guide me in the right direction? https://gyazo.com/77cfe12649ba6c3fa9a0048b3f56b857

Answer 1

1) Sum of angles of a triangle is 180°

2) Angles opposite equal sides of a traingel are equal.

3) The sum of the measures of a linear pair of angle is 180°

The rest is algebraic manipulation of the values.
