Question

5. Find the value of x for which ABCD must be a parallelogram.-9 - 6xx-30

Answer 1

Step-by-step explanation

we will apply the parallelogram laws to answer the given question

For the question

So applying the above

`-9-6x=x-30`

Solving for x

`\begin{gathered} -6x-x=-30+9 \\ -7x=-21 \\ \\ x=-(21)/(-7) \\ \\ x=3 \end{gathered}`

The value of x = 3
