Question

PQR is a triangle, right-angled at p.if PQ=10cn and PR= 24 cm find QR. what is the answer​

Answer 1

Step-by-step explanation:

By pythagoras theorem

QR =26cm

Answer 2

Answer

26 cm

Explaination:

Given: PQ=10cm, PR=24cm

Let QR be x cm.

In right angled triangle QPR,

(Hypotenuse)  square  =(Base) square  +(Perpendicular)  square

 [By Pythagoras theorem]

(QR)  square =(PQ)  square +(PR)  square

⇒x  square =(10) square+(24)  square

 ⇒x  square=100+576=676

⇒x=  root 676  =26cm

Thus, the length of QR is 26cm
