The sides of right triangle are x,x-1,x+1units find these​

Answer»

Step-by-step explanation:

Clearly if x units is a SIDE of square , it will be a positive number

→x-1

Since , these are the are SIDES of a right angle ∆

→ x+1 units MUST be the hypotenuse .

So , by Pythagoras theorem

(x+1)^2= x^2+(x-1)^2

→x^2+1+2x = x^2+x^2+1-2x

→2x+2x=x^2

→4x=x^2

→x^2-4x=0

→x(x-4)=0

→x=0

or , x=4

→The REQUIRED sides are

•x units =4 units

•x-1 units = (4-1) units =3 units

•x+1 units =(4+1)units =5 units
