Ok, so

We got the following parallelogram:

We want to find the value of the angle BCD.

For this, remember that the sum of the internal angles of a parallelogram must be always equal to 360°.

So, we could write:


\begin{gathered} 2x+2x+x+x=360 \\ 6x=360 \\ x=(360)/(6) \\ x=60 \end{gathered}

The value of x is equal to 60°. Now, the angle BCD is an angle that measures 2x degrees.

So, BCD measures 2*60, which is 120°.
