Answer:
-7/5
Step-by-step explanation:
From the Special Triangle Theorem, the hypotenuse is equal to the side lengtht times the Sqrt(2).
So hypotenuse H = xSqrt(2), x=H/Sqrt(2).
Using numbers, if H = 7, then x = 7/Sqrt(2) = 7Sqrt(2)/2 to rationalize it.
x=
Step-by-step explanation:
add6 to both sides of the = sign (only to like terms, or terms without the x)
22+6 is 28
so 28=7x
divide both sides by 7
which is 4
