Answer is angAOC=90
Is A O B is in one line so
2a+62+54-a+5a-20=180
6a=180-62+20-54=84
a=14
angAOC= 2a+62=90
angCOD=54-a=40
angDOB=5a-20=50
SO angAOC is the biggest
Explanation:
If 
then taking the reciprocal gives
The equation of a circle is just (x-h)^2+(y-k)^2= r^2
in place of h you just put the x-coordinate of the center
in place of k you put the y-coordinate of the center
and in place of r you put the radius
So your answer is just (x-1)^2+(y-4)^2=4 (first choice)
