Answer 2

Answer:

26 cm

Step-by-step explanation:

Given : PQR is a triangle, right angled at P.

To Find:If PQ=10cm and PR=24cm, find QR

Solution:

Refer the latched figure

Perpendicular = PQ = 10 cm

Base = PR = 24 cm

Hypotenuse = QR

Now to find QR we will use Pythagoras theorem

$Hypotenuse^2=Perpendicular^2+Base^2$

$QR^2=PQ^2+PR^2$

$QR^2=10^2+24^2$

$QR^2=676$

$QR=\sqrt{676}$

$QR=26$

Hence QR = 26 cm.
