Answer:
4 units
Step-by-step explanation:
The picture of the question in the attached figure
we know that
Triangle PTQ≅Triangle RTS
Remember that
If two figures are congruent, then its corresponding sides and the corresponding angles are congruent
so
PQ≅RS
we have
[tex]RS=4\ units[/tex]
therefore
[tex]PQ=4\ units[/tex]
