Question

In the right - angled ∆PQR, ∠ P=90°. If ℓ(PQ) = 24cm and ℓ(PR) = 10cm. Find the length

of seg QR.

a) 26cm

b) 28cm

c) 29cm

d) 30cm​

Answer 1

Answer:

ᴀ. 26

Step-by-step explanation:

ɪɴ ᴛʀᴀɴɢᴇ ᴘǫʀ ʙʏ ᴘʏᴛᴀʜɢᴏʀᴀs ᴛʜᴇᴏʀᴇᴍ..

${pr}^{2} + {pq}^{2} = {qr}^{2} \\ \\ on \: putting \: values \\ {qr}^{2} = {24}^{2} + {10}^{2} \\ {qr}^{2} = 576 + 100 \\ {qr }^{2} = 676 \\ qr = \sqrt{676} \\ qr = 26$
