Answer:

x = 4

Step-by-step explanation:

Note that the diagonals of a parallelogram bisect each other. They cut each other into two equal parts.

For QS, we can find x as per below;


\begin{gathered} 8=2x \\ (8)/(2)=(2x)/(2) \\ 4=x \\ \therefore x=4 \end{gathered}

For RT,


\begin{gathered} 3x=12 \\ (3x)/(3)=(12)/(3) \\ \therefore x=4 \end{gathered}

So x = 4
