Question

I need help with math

Answer 1

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}
