I am 13, 5 foot, and 91 pounds. Is that okay? Or is it too big or too little?​

dunno and don’t care

Step-by-step explanation:

Part A : x = 26

Part B : AB = 64  

Step-by-step explanation:

Part A,

By the theorem,

"Perpendicular drawn from the center of a circle to the chord is a bisector of the chord."

Since ON is a perpendicular to the chord AB,

AN = BN

x + 6 = 2x - 20

x = 2x - 20 - 6

x = 2x - 26

x - 2x = -26

-x = -26

x = 26

Part B,

Length of AB = (x + 6) + (2x - 20)

                      = 3x - 14

For x = 26

AB = (3×26 - 14)

     = 78 - 14

     = 64

Therefore, Option (D) will be the answer.
