Question

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

Answer 1

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
