As PRQ is right side we have:
PR^2 + PQ^2 = RQ^2
(PS +SR)^2 + 12^2 = 20^2
(PS +SR) = 16
We know That in a triangle, the summation of each two sides is more than the third one, so:
12 < PS + QS
20 < SR + QS so 20- 8 < (SR-8) + QS
From above two equations, we recognize that SR is at least 8 more than PS. So SR is more than PS.
NOT SURE IT'S CORRECT OR NOT

how can you make sure "20- 8 < (SR-8) + QS" ?

I think the ans is D.

if we cut PR into half >>> PS=SR=8

then QS would be around 14. which is applicable for a right trianle with sides 12-8-14.XX

Correct answer is B right?
45 = 1/2b (12) so PS is 7.5
12^2 + b^2 = 20^2 b or PR is 16
RS = PR - PS (16-7.5)= 8.5 is RS
