Question

WILL MAKR BRIANLIEST IF RIGTH!!!

Answer 1

3 units

Explanation:

By intersecting chords theorem:

`AE * EB = CE * ED`

`\therefore 3 * 4= x * (x+1)`

`\therefore 12= x^2 +x`

`\therefore x^2 +x-12=0`

`\therefore x^2 +4x-3x-12=0`

`\therefore x(x +4)-3(x+4)=0`

`\therefore (x +4)(x-3)=0`

`\therefore (x +4)=0, \: (x-3)=0`

`\therefore x=-4, \: x=3`

Since, the value of x can not be negative.

`\therefore x\\eq - 4`

`\implies x = 3`

`\implies CE = 3`
