Question

In the given figure ∠Q= 900, PQ= 8cm, QR=10 cm, PR =12cm then the value of 90 –​

Answer 1

Answer:

PR=10cm

Step-by-step explanation:

It is given that

PQ=8cm and QR=6cm

∠PQR=90∘

Using Pythagoras Theorem

PR 2 =PQ 2 +QR 2

Substituting the values

PR 2 =8 2 +62

By further calculation

PR 2 =64+36=100

PR=√100

So we get

PR=10cm
