Yes

Answer 4

Then, if a diameter is perpendicular to a chord, it bisects the chord and its arcs.

So 6(2) = x(x)

Answer 5

Both pieces of the chord are equal, we call both of them x, as they are equal in length.

Answer 6

so x^2 = 12,

and you can find what x is equal to.

Answer 7

Ok. So x equals 12 then?

Answer 9

what number when squared will give you 12?
