type this into desmos...then type each point in a separate window....the one that is ON the circle will be your answer here.

*hint, use desmos
A=(4,-2)
B=(-8,6)
midpoint(A,B)
OR
midpoint((4,-2),(-8,6))

1

use distance((-2,4),(6,10)) in desmos...that gives the length of the diameter...
then divide that number in 1/2 to get the radius of the circle.

Write your answer in x,y form.

x=108, y=72

x=72, y=108

x=60, y=120

x=120, y=60

remember to find the sum of the angles (sum = (#sides-2)*180)...then subtract all the angles given from the total sum.

Make an educated guess if necessary...go into show your work and make a path from A to B to G to determine exactly what angle they're asking for....is it obtuse? is it acute?
