Let one side = x cm. Then,
Second side = x + 7 cm.
Hypotenuse = 17 cm. (Given)
According to the Pythagoras theorem,

=
=
=
=
= Dividing this equation by 2, we get
=
=
= . So, either (x+15) or (x-8) = 0.
So, x = -15 or x = 8. But x cannot be equal to -15 as it is not a real No.
So, . So one side = 8 cm. and another side = 15.
I think, it is clear to you now. All the best. Feel free to contact me at gsmani9@yahoo.com as I am a home tutor in India.
