2. Write the equation of a circle that has a diameter of 12 units if its center is at (4,7).
ahrayia [7]

Answer:

The Answer is B

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here diameter = 12, thus radius = 12 ÷ 2 = 6 and (h, k) = (2.5, - 3.5), thus

(x - 2.5)² + (y - (- 3.5))² = 6², that is

(x - 2.5)² + (y + 3.5)² = 36 ← equation of circle

1a. x = 70 
     Alternate Interior Angles

1b. x = 120
     Alternate Interior Angles

1c. x = 110
     Corresponding Angles

2a. x = 100
      Alternate Interior Angles
      y = 80
      Supplementary Angles (with x)

2b. x = 75
      Corresponding Angles
      y = 105
      Supplementary Angles (with x)

2c. x = 70
      Same-Side Interior Angles 
      y = 110
      Supplementary Angles (with x)

Try the rest on your own!
