The equation of a circle with center (h,k) and radius r is
convert it to that form by comleting the square for the x and y terms
or, we can just expand what we know
expand
and make it equal to 0
so expanding we get
minus m^2 from both sides
arranging in decreasing power order with m² at the end
that is option A

Answer: 3
Step-by-step explanation:
Triangle DCB is similar to Triangle ECA by AAA.
Since EA and DB are parallel lines, that makes Angle CDB = Angle CEA and Angle CBD = Angle CAE because they are corresponding angles.
Since the two triangles are parallel, we can set up a ratio.
Now we plug in the numbers given.
Now we can cross multiply
6CA = 72
Therefore, CA = 12.
AB = CA - CB
So AB = 12 - 9
AB = 3
