Question

3
Solve any one of the following subquestions :
In the figure,
PS = 3, SQ = 6, QR = 5, PT = x and TR = y. Give any two pairs of
values of x and y such that line ST || side QR.
​

Answer 1

Step-by-step explanation:PS/SQ=3/5

or SQ/PS=5/3

SQ/PS+1=5/3 +1

SQ+PS/PS=5+3/3

PQ/PS=8/3

If

ST||QR

Then

∆PQR≈∆PST

So,

PQ/PS=PR/PT

8/3=28/PT

PT=28*3/8=10.5...
