Since diagonals bisect each other, both halves of a diagonal have the same length.

Answer:
x = ![\sqrt{3}](https://tex.z-dn.net/?f=%5Csqrt%7B3%7D)
Step-by-step explanation:
the ratio of side to hypotenuse in a right triangle is 1 : ![\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D)
in this problem we can use 'x' in place of 1 and
in place of
to create a proportion like this:
1/x =
/![\sqrt{6}](https://tex.z-dn.net/?f=%5Csqrt%7B6%7D)
cross-multiply to get:
·x = ![\sqrt{6}](https://tex.z-dn.net/?f=%5Csqrt%7B6%7D)
x = ![\frac{\sqrt{6}}{\sqrt{2}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%7B6%7D%7D%7B%5Csqrt%7B2%7D%7D)
x = ![\sqrt{3}](https://tex.z-dn.net/?f=%5Csqrt%7B3%7D)

Answer:
n = 1/2
Step-by-step explanation:
So the equation is 4/5n - 1/5 = 2/5n.
So, the first thing that we need to do is get the variable on one side.
So, to do that we need to subtract 4/5n on both sides.
Now our equation is -1/5 = -2/5n
Now the last step is to simplify.
To do that, we need to multiply by the reciprocal of 2/5 on both sides.
That leaves us with 1/2 = n
