Question

I need help with math

Answer 1

Answer:

Step-by-step explanation:

7) The lengths of the tangent from an external point to a circle are  equal.

      2x - 1 = x + 10

           2x = x + 10 + 1

           2x = x + 11

      2x -x  = 11

             $\sf \boxed{\bf x = 11}$

8) Radius : XC

    Chord: CB

   Diameter : AB

  Name of the circle: X    {a circle is named by its center}
