Respuesta :

Answer:

40°

Step-by-step explanation:

A parallelogram is a quadrilateral (a four-sided object) with parallel sides

Some of the characteristics of a parallelogram includes:

1. Opposite sides and angles are congruent.

2. Opposite angels are congruent  

3. Consecutive angles are supplementary  

4. The diagonals bisect each other

Angle DBC = ABD = 35 (alternate angles are equal)

Angle ADB = 180 - 35 - 105 = 40

I subtracted from 180 because sum of angles in a triangle is equal to 180
