Answer:
angle A = angle C [properties of parallelogram]
angle B = angle D [properties of parallelogram]
angle A+ angle B = 180° [linear pair]
65° + angle B = 180°
angle B = 180° -65°
angle B = 115°
angle B = angle D [properties of parallelogram]
angle B + angle D = 2(angle B)
angle B + angle D = 2(115°)
angle B + angle D = 230°
230° is the answer
