6. Angle C is half the arc, so 60 degrees,

B = 180-A-C = 180-42-60 = 78 degrees

Answer: C

7.

Complete the square.

`x^2+y^2 + 8x-8y+24 = 0`

`x^2 + 8x + y^2-8y = -24`

`(x^2 + 8x + 16) + (y^2 - 8y + 16) = -24 + 16 + 16`

`(x+4)^2+(y-4)^2=8`

A. radius=4; nope r=√8

B. r=2√2 yes that's the same as √8. SELECT B

C. No the center is at (-4,4)

D. Yes, SELECT D
