Question

(1) In APQR, ST|| QR, 1(PS) = 2.5/
I(SQ) = 5. Find = pt/tr​

Answer 1

Answer:

3.7 cm

Step-by-step explanation:

PS = 4cm

SQ = 6cm

PT = 2.5cm

TR = ?

By B.P.T Theorem we know that, \frac{AD}{DB} =\frac{AE}{EC}

DB

AD

=

EC

AE

Here,

\begin{gathered}\frac{PS}{SQ} =\frac{PT}{TR} \\\\\frac{4}{6} =\frac{2.5}{TR}\end{gathered}

SQ

PS

=

TR

PT

6

4

=

TR

2.5

TR = 2.5 x 6 / 4 = 15/4 = 3.7

TR = 3.7cm
