Answer:

[tex]x=4\sqrt{2}\ cm[/tex]

Step-by-step explanation:

we know that

An isosceles triangle has two equal sides

Let

x ----> the length of the leg

Applying the Pythagorean Theorem

[tex]c^2=a^2+b^2[/tex]

where

c is the hypotenuse (the greater side)

a and b are the legs of the right triangle

In this problem we have

[tex]c=8\ cm[/tex]

[tex]a=b=x\ cm[/tex]

substitute

[tex]8^2=x^2+x^2\\\\64=2x^2\\\\x^2=32\\\\x=\sqrt{32}\ cm[/tex]

simplify

[tex]x=4\sqrt{2}\ cm[/tex]
