Center of a circle is a midpoint of line connecting two endpoints so center is:
(12,-14) (2,4) we divide those two points by two
C(a,b)- center
C(a,b)=((12+2)/2),(-14+4)/2)=(7,-5)
Radius is the distance from the center to any point on the circle:
we take point (2,4)
r=
Answer:
A linear pair is a pair of adjacent angles formed when two lines intersect
X times .3=12 So X equals 12/.3 which is 40. Another way of solving it is dividing 12 by 3 which is 4 then multiply by ten.
