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
136*2+x*2=360


So firstly, solve the multiplications:
2x+272=360


Next, subtract 272 on each side:
2x=88


Finally, divide 2 on each side of the equation, and your answer should be
x=44




In short, ∠BCD is 44°
