Well, since triangles $PQT$ and $PRS$ are similar (All three angles equal) I think that the proportion will also be the same between the sides.

$QT$ over $RS$ is 8/10, so the proportion of $PT$ over $PS$ should also be 8/10 (or 4/5) methinks.

Correct me if I'm wrong :)

That's correct (see similar triangles for a reference if you like). – gnometorule Feb 24 '13 at 17:04

Triangle PRS similar to PQT.(Since all angles are equal.)


PT/PS= 8/10=4/5 .
