Question

pqr is a triangle a is a point on pq such that pa = 1/4pq anf b is a poiny of pr such that pb=1/4pr . prove that ab=1/4qr​

Answer 1

Answer:

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^2Hypotenuse

2

=Perpendicular

2

+Base

2

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

2

=PQ

2

+PR

2

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

2

=10

2

+24

2

QR^2=676QR

2

=676

QR=\sqrt{676}QR=

676

QR=26QR=26

Hence QR = 26 cm.
