37. Which is an equation for the circle with a center
at (-2, 3) and a radius of 3?
A. x2 + y2 + 4x –6y+22=0
B. 2x2 + 2y2 + 3x – 3y+4=0
C. x2 + y2 + 4x -6y+4=0
D. 3x2 + 3y2 + 4x -6y+4=0

C

Step-by-step explanation:

(x+2)² + (y-3)² = 3²

x² + y² + 4x - 6y + 4 + 9 - 9 = 0

x² + y² + 4x - 6y + 4 = 0

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.

answer is c
