Question

PQR is a right angled triangle. If the lengths of two of its sides are 12cm and 5cm, what is the length of its third side?? ​

Answer 1

Answer:

13 cm

Step-by-step explanation:

In an hypotenuse triangle,

pq=root rq*2+pr*2

= root 144+25

= root 169

=13cm

Hence solved

Answer 2

Answer:13

Step-by-step explanation:

in ∆PQR let PQ=12&QR=5

then we have to find PR

PR=PQ^2+QR^2

PR= (12)^2 + (5)^2

PR^2 =144+25

PR^2= 169

PR=13

therefore PR=13 cm

hope this help u
