Question

PQRis a right angled at Rif PR= 5 cm and
QR = 12 CM then length of the PQ is
O 13
O 17
O
7
O
None of these​

Answer 1

Answer:

13 is the correct answer by Pythagoras theorem

Answer 2

Answer:

PQ=13cm

Step-by-step explanation:

given,

PQR is a right angled triangle

PR=5cm

QR=12cm

                                      by Pythagoras theorem:

  PQ^2=PR^2+QR^2

           =5^2+12^2

           =25+144

           =169

                                      taking square root both side:

PQ=under root 169

    =13cm
