Hope I helped

Answer 2

Answer: The measure of angle BCD is 77 degree.

Explanation:

From the given figure it is noticed that the side AB and DC are parallel and side AD and BC are parallel. So the given figure is a parallelogram.

It is given the measure of angle BCD is 103 degree.

According the property of parallelogram, any two consecutive angles of a parallelogram are supplementary angles.

Since the given figure is a parallelogram therefore angle ABC and angle BCD are supplementary angles.

$\angle ABC+\angle BCD=180$

$103+\angle BCD=180$

$\angle BCD=180-103$

$\angle BCD=77^{\circ}$

Therefore, the measure of angle BCD is 77 degree.
