The correct options regarding the circle with endpoints of the longest chord at (4, 5.5) and (4, 10.5) are:

The center is (4,8).

The radius is of 2.5 units.

$(x - 4)^2 + (y - 8)^2 = 6.25$

<h3>What is the equation of a circle?</h3>

The equation of a circle of center $(x_0, y_0)$ and radius r is given by:

$(x - x_0)^2 + (y - y_0)^2 = r^2$

The center is the <u>midpoint of the chords</u>, hence:

$x_0 = \frac{4 + 4}{2} = 4$ .

$y_0 = \frac{5.5 + 10.5}{2} = 8$ .

The radius is half the distance between the chords, hence:

$r = 0.5\sqrt{(4-4)^2 + (10.5 - 5.5)^2} = 0.5 = 2.5$ .

Hence the equation is:

$(x - x_0)^2 + (y - y_0)^2 = r^2$

$(x - 4)^2 + (y - 8)^2 = 2.5^2$

$(x - 4)^2 + (y - 8)^2 = 6.25$

Which pair of angles are adjacent angles?

Sloan [31]

Your answer is B. 1 and 3.
This is because adjacent angles are angles that could form one angle if the line inbetween them was removed, which means they have a common side. Angles 1 and 3 are the only angles out of the options that have a common side, so they must be the answer.

I hope this helps!
