Answer: 5;12;13

Step-by-step explanation:

let's call the shortest leg

[tex]x[/tex]

and then the longer leg and the hypotenuse

[tex]2x + 2[/tex]

[tex]2x + 3[/tex]

respectively, and then apply pythagorean theorem to the triangle:

[tex]x^2+(2x+2)^2=(2x+3)^2[/tex] at this point is simple number crunching;

[tex] x^2+4x^2+8x+4=4x^2+12x+9 \\ x^2-4x-5=0 \rightarrow (x-5)(x+1)=0[/tex]

the only valid solution is obviously x=5 since its a length of a segment.
