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:
a is 6 meters, so replacing a with 6 and solving we get:
To simplify the surd, we can use the property shown below:

Now simplifying:
