Since in a parallelogram the sum of the angles belonging to one side is 180, the angle BAD = 180 – ABC = 180 – 130 = 50.
The external angle KAB will be equal to: KAB = 180 – BAD = 180 – 50 = 130. The external angle of the parallelogram is equal to one of its internal corners.
Answer: The outer corner is 130.
