Find the length of each leg. Leave an answer in simplest radical form.

Answer:
[tex]x=8\sqrt{2}[/tex] units
Step-by-step explanation:
The given triangle is an isosceles right triangle.
This implies that, the second leg is also x units.
We use the Pythagoras Theorem to obtain:
[tex]x^2+x^2=16^2[/tex]
[tex]2x^2=256[/tex]
Divide both sides by 2; to get
[tex]x^2=128[/tex]
Take positive square root to get:
[tex]x=\sqrt{128}[/tex]
[tex]x=8\sqrt{2}[/tex]
