Question

pqr is a triangle right angled at q if pq = 5cm qr = 12 cm find pr pls help meeeee

Answer 1

Step-by-step explanation:

$In \: right \: angled \: ∆PQR-$

$From \: pythogoras \: theorem:-$

$\small\boxed{कर्ण²=आधार²+लम्ब²}$

$PR² = PQ² + QR²$

$PR = \sqrt{PQ² + QR²}$

$PR = \sqrt{5² + 12²}$

$PR = \sqrt{25+144}$

$PR = \sqrt{169}$

$PR = 13 \: cm$

Answer 2

Answer:

pqr-180

Pq-5cm

qr-12cm

PR-?

Step-by-step explanation:

sum of angle of a triangle =180

pq+qr+pr=180

5cm+12cm+?=180

17cm+?=180

?=180-17

?=163

{PR=163 }
