Answer 2

Answer:

ANSWER

Let one side be xcm.Since the difference between the two sides is 7cm

∴ the other side=x+7cm

As the given triangle is a right angled triangle with hypotenuse =17cm

By using pythagoras theorem, we get

x

+(x+7)

+15x−8x−120=0

⇒x(x+15)−8(x+15)=0

⇒(x+15)(x−8)=0

⇒x=−15 or x=8

x=−15 cannot be negative

∴x=8

Hence the two sides of the triangle are 8cm and 15cm
