Answer:

80°+angle CBA=180°

CBA= 180-80

CBA= 100°

The parallelogram has the following properties: Opposite sides are parallel by definition. Opposite sides are congruent. Opposite angles are congruent.

Thus,

Angle CDA= 100°

Angle DCB=DAB

DCB + CDA=180° as they're adjacent angles.

DCB + 100 =180°

DCB =180-100

Angle DCB = 80°

Angle DAB =80° as the Opposite angles in a parellelogram are congruent.
