Question

In ∆PQR, angle PRQ =90°, seg RS parallel to side PQ, SP = 4 units, QS =9 then find SR​

Answer 1

Answer:

We have using Pythagorus theorem,

SR²=PS.QS..(1) [ Can be proved by applying Pythagorus theorem on the triangles ΔPQR, ΔPQS, ΔQSR]

Given PS=4,QS=9.

Then form (1) we have

SR² =4×9

or, SR² =36

or, SR=6,
