It should be noted that the angle at the center of the circle is twice the angle at the circumference.
<h2>
Circle Theorem</h2>
It should also be noted that the angle in a semicircle is a right angle. Angles that are in the same segment are equal.
Furthermore, the opposite angle that is in a cyclic quadrilateral sum is 180°. The angle between the chord and the tangent is also equal to the angle in the alternate segment.

(a/b)=c
first multiply both sides by b
b*(a/b)=c*b
this cancels out the b under the a
a=cb
Then divide by c
a/c=(cb)/c
this cancels the c and leaves b by itself
b=(a/c)
