Given: One leg of isosceles right triangle = 5 inches
Since in isosceles right triangle , two sides have same side length , therefore the length of the other leg should be 5 inches.
Let H be the hypotenuse of the isosceles right triangle
Now, by Pythagoras Theorem , we have

Hence, the approximate length of the hypotenuse = 7.1 inches
