Answer:
Hey there!
This is a parallelogram, and we have the angles next to each other add to 180 degrees. Angle ABC+Angle BCD=180
103+x=180
x=77
BCD=77 degrees.
Let me know if this helps :)
Answer: 77 degrees
Explanation:
interior angles on the same side of transversal are supplementary. Thus,
x = 77
