Answer:
option C.
Step-by-step explanation:
According to equidistant chords theorem, two chords of a circle are congruent if and only if they are equidistant from the center of the circle.
Congruent means they are equal in length.
Using equidistant chords theorem, we can fill the blank.
In a circle, two chords that are equidistant from the center of the circle are always equal in length.
Therefore, the correct option is C.
Du to the triangle is an Equilateral triangle, both angles are equal.
Now we have a straight angle RTU which equals 180 degrees so,
<RTS + <STU = 180
5x + 5x -30 = 180
10x = 210
x = 21
The general equation of the circle is:
(x -xo)^2 + (y - yo)^2 = r^2
Where xo,yo are the coordinates of the center and r is the radius of the circle.
Here (xo,yo) is (-16,30) and you can find the radius.
You can find the radius using the equation of the distance (Pythagoras) between the center (-16,30) and any point on the circunference. Here use (0,0)
r^2 = (-16 - 0)^2 + (30 - 0)^2 = 1156
Then, the equation is>
(x - (-16) )^2 + (y - 30)^2 = 1156
=> (x + 16)^2 + (y - 30)^2 = 1156. <----- answer
