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

OR

midpoint((4,-2),(-8,6))

Question 11

11.

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.

What is the center point of the circle whose equation is

(2, -3)

(2, 2)

(-2, 3)

(6, 6)

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

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.

134

Look at the size of the angle...which of the choices is it closest to if you compare it to a 90 degree angle

125

135

100

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?
