Answer:
Let the three numbers be x,y and z
It is given
x^2+y^2=26×2=52....(1)
y^2+z^2=100....(2)
z^2+x^2=80...(3)
from ,(2)
y^2=100-z^2
put this value of y^2 in (1)
x^2+100-z^2=52
x^2-z^2=-48
Add this equation to (3) you will get
2x^2=32 which gives x=4
Put this value of x in equation (1) and (3) you will get y=6 and z=8
So the numbers are 4,6,8
