Answer:

[tex]x=3\sqrt{2}[/tex]

Step-by-step explanation:

In a right triangle, the "hypotenuse" is the side opposite of the 90 degree angle. That side is "a"

Using pythagorean theorem, we can write:

Leg^2 + Leg^2 = Hypotenuse^2

Note: legs are the other 2 sides, x and x respectively

Now we can write:

[tex]x^2 + x^2 = a^2[/tex]

a is 6 meters, so replacing a with 6 and solving we get:

[tex]x^2 + x^2 = a^2\\2x^2=6^2\\2x^2=36\\x^2=18\\x=\sqrt{18}[/tex]

To simplify the surd, we can use the property shown below:

[tex]\sqrt{x*y}=\sqrt{x}  \sqrt{y}[/tex]

Also

[tex]\sqrt{x} \sqrt{x} =x[/tex]

Now simplifying:

[tex]x=\sqrt{18} \\x=\sqrt{9*2}\\ x=\sqrt{9} \sqrt{2} \\x=3\sqrt{2}[/tex]
