Find value of the unknown ...

Answer:
B=48, A=106
Step-by-step explanation:
Using A and B as the unknown variables, not the point names.
The lines in the angles of B and D mean that those angles are congruent, or the same. B=D, so B=48. The lines are the same length, as marked with the arrows, which leads to unknown variable A=106, like point A shows.
Answer:
a = 106, b = 48
Step-by-step explanation:
The opposite angles of a parallelogram are congruent, thus
∠ A = ∠ C , that is
a = 106
∠ ADB = ∠ DBC ( alternate angles ) , so
b = 48
