Question

in a right angle triangle pqr angle Q is equal to 90 degree if PQ is equal to 15 CM QR is equal to 8 centimetre find PR​

Answer 1

$\huge \boxed{ \bf{ANSWER}}$


$\bf \underline{ Given} \: \div$

PQ =15 cm, QR = 8 cm.


${\bf \underline{ \: To \: Find }} : \: PR$


As the triangle is a right angled triangle.

So by Pythagoras theorem

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

${ PR} ^{2} = {15}^{2} + {8}^{2}$

${ PR }^{2} = 225 + 64$

${ PR }^{2} = 289$

$PR = \sqrt{289}$

$PR = 17$


Therefore , length of the hypotenuse = 17cm

Answer 2

The length of PR is 17 cm

Step-by-step explanation:

We are given that in a right angle triangle pqr angle Q is equal to 90 degree

So, PQ = Perpendicular

QR= Base

PR = Hypotenuse

PQ=15 cm

QR = 8 cm

To find the length of Hypotenuse We will use Pythagoras theorem

$Hypotenuse^2=Perpendicular^2+Base^2\\PR^2=PQ^2+QR^2\\PR=\sqrt{15^2+8^2}\\PR=17$

Hence The length of PR is 17 cm
