Check the picture below, so the circle looks more or less like that one.
well, the center of it is simply the Midpoint of those two points, and its radius is simply half-the-distance between them.
BD = 53, AC = 45 & DA = 87. Find BC

Answer: The equation of the circle =
x² + y² + 6x - 4y + 9 = 0
Step-by-step explanation:
We have
angle 1=
see the attached picture to better understand the problem
we know that
<span>Vertical angles are congruent

<span>
and
adjacent angles are supplementary
</span>
<span>
if the measure of one of the angles is </span>
degrees and straight lines equal 
<span> degrees you have to
subtract </span> from
so
therefore
the answer is
the measures of the other three angles are
