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
