Step-by-step explanation:
In any circle the ratio of the arc length to the circumference of the circle is equal to the degree measure of the arc to 360°
One pair of opposite sides both parallel and congruent implies a parallelogram.
+ √6 = √9
The first step is to get by itself. We can do this by subtracting 
from each side, and simplifying 
= 3 -
Now we square both sides
5x = (3 - )²
Using the formula (a - b)² = a² -2ab + b², (3 - )² = 15 - 6
5x = 15 - 6
x =
