So for this, remember that
1. a property for parallelograms is that opposite angles are congruent
and 2. all angles add up to 360
Using this info, we can form the equation

So firstly, solve the multiplications:

Next, subtract 272 on each side:

Finally, divide 2 on each side of the equation, and your answer should be

In short, ∠BCD is 44°
