Answer: 7.1 inches

Explanation:

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

$H^2=5^2+5^2=25+25=50\\\\\Rightarrow\ H=√(50)=5√(2)\\\\\Rightarrow\ H==5*(1.41421356237)\\\\\Rightarrow\ H==7.07106781187\approx7.1\ inches$

Hence, the approximate length of the hypotenuse = 7.1 inches
