Answer:
Radius = 5
center is (19,-1)

Step-by-step explanation:
Two points in the plane, (19,4) and (19,−6), represent the endpoints of the diameter of a circle.
Distance between the points is calculated using formula


diameter = 10
radius = diameter divide by 2
Radius = 5
midpoint is the center of the circle


(19,-1)
Equation of the circle

h,k is the center and r is the radius
h=19 and k=-1 , r=5

In quadrant 2 is where it lies.

Which of the following best<span> represents a rotation
</span>
B.
Given:
m∠NRQ = 60°
To find:
The angle measure of minor arc NQ
Solution:
The inscribed angle is half of the intercepted arc.

Multiply by 2 on both sides.


Substitute m∠NRQ = 60°.


The measure of minor arc NQ is 120°.
