Algebra Find the value of y. Express in simplest radical form. Show work.

Given:
Here right angle triangle is given with two equal sides 8
Require:
We have to find the value of y
Explanation:
In this sum
we have to use Pythagoras theorem
which is the addition of square of both side is equal to the square of hypotenuse
now here
[tex]8^2+8^2=y^2[/tex][tex]64+64=y^2[/tex][tex]128=y^2[/tex][tex]\sqrt{128}=y[/tex][tex]8\sqrt{2}=y[/tex]Final answer:
The value of y is
[tex]y=8\sqrt{2}[/tex]
