In parallelogram ABCD ,
Angle D = 115°(given )
angle B = Angle D ( opposite angle of a parallelogram are equal )
therefore , angle B = 115°
angle A = 180- angle D
=180- 115
=65 °
Angle D = 115°(given )
angle B = Angle D ( opposite angle of a parallelogram are equal )
therefore , angle B = 115°
angle A = 180- angle D
=180- 115
=65 °
