Question

in triangle pqr,s and t are two points on pq and pr and respectively such that ps=4cm,sq=3cm,pt=6cm,tr=4.5cm angle pst=40degree find angle pqr​

Answer 1

Step-by-step explanation:

In △PQR, we have

SQ

PS

=

3

4

TR

PT

=

4.5

6

=

3

4

SQ

PS

=

TR

PT

∴ST∣∣QR (∵ Converse of Thales theorem)

Therefore, ∠PST=∠PQR=40

o

(∵ Corresponding angles)
