Answer:
It is A), because I learned this before. Plz give brainliest!!
Also, Hope this helps! (:
The one you have highlighted, the y values are the range values
The correct options regarding the circle with endpoints of the longest chord at (4, 5.5) and (4, 10.5) are:
- The radius is of 2.5 units.
<h3>What is the equation of a circle?</h3>
The equation of a circle of center 
and radius r is given by:
The center is the <u>midpoint of the chords</u>, hence:
.
.
The radius is half the distance between the chords, hence:
.
Hence the equation is:

Using our congruency statement <span>DEFGH ≅ QRSTU, we can see which angles map onto each other.
</span>D ≅ Q
E ≅ R
F ≅ S
G ≅ T
H ≅ U
We see that E ≅ R, and since E is 143 degrees, R = 143 degrees.
Why is this true, you may ask? When dealing with congruency, the given points/letters (they are really both) are congruent to the corresponding shapes letter/point. For example, if triangle ABC ≅ DEF, A would correspond to D, B would correspond to E, etc. When you see these types of problems, congruency will be applied to angles (it could apply to lines in other cases).
If you have any questions, feel free to ask!
