Question

ΔPQR is right angled at Q. If PR= 13cm and QR= 5cm, find the length of PQ.

Answer 1

Answer:

12cm

Step-by-step explanation:

Let PR be the hypotenuse.

Let QR be the base.

We know, in a right angled triangle, hypotenuse ²=height²+base²

We have to find the height i.e. PQ.

So, PQ² = PR²-QR²

=13²-5²

=169-25

=144cm

So PQ = √144 cm

=12cm
