Question

in the figure QR is equal to 8 cm angle Q is equal to 56 degree angle R is equal to 68 degree what is the measure of angle P what is the length of PR what is the perpendicular distance from P to Q R what is the area of the triangle pqr​

Answer 1

Step-by-step explanation:

Given that:

QP=8cm,PR=6cm and SR=3cm

(I) In △PQR and △SPR

∠PRQ=∠SRP (Common angle)

∠QPR=∠PSR (Given that)

∠PQR=∠PSR (Properties of triangle )

∴△PQR∼△SPR (By AAA)

(II)

SP

PQ

=

PR

QR

=

SR

PR

(Properties of similar triangles)

⇒

SP

8cm

=

3cm

6cm

⇒SP=4cm and

⇒

6cm

QR

=

3cm

6cm

⇒QR=12cm

(III)
