∠a + ∠d = 180 Definition of linear pairs or straight angles

∠d + ∠c = 180 Definition of linear pairs or straight angles

∠a + ∠d = ∠d + ∠c Substitution

∠a = ∠c Subtraction

Answer:

(x+1)^2+(y+1)^2=13

Step-by-step explanation:

Equation of a circle: (x – h)^2 + (y – k)^2 = r^2

center: (-1, -1)

radius: sqrt(6^2+4^2)/2=sqrt(52)/2=2sqrt(13)/2=sqrt(13)

Substitute those values in to get

(x+1)^2+(y+1)^2=13
