What is the value of x in QRST? R 3x 2x T S 4 8 12 Od 16

Answer:
x = 4
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;
[tex]\begin{gathered} 8=2x \\ \frac{8}{2}=\frac{2x}{2} \\ 4=x \\ \therefore x=4 \end{gathered}[/tex]For RT,
[tex]\begin{gathered} 3x=12 \\ \frac{3x}{3}=\frac{12}{3} \\ \therefore x=4 \end{gathered}[/tex]So x = 4
