find the missing pieces of the parallelogram for number 9

Given:
[tex]\bar{HQ}=12,\bar{NQ}=8[/tex]Required: Lengths of PQ and QO
Explanation:
The diagonals of a parallelogram bisect each other.
So,
[tex]\bar{PQ}=\bar{NQ}\text{ and }\bar{MQ}=\bar{QO}[/tex]Therefore,
[tex]\bar{PQ}=8,\bar{QO}=12[/tex]Final Answer:
[tex]\bar{PQ}=8,\bar{QO}=12[/tex]
