WILL MAKR BRIANLIEST IF RIGTH!!!

Mathematics
1 answer:
kicyunya [14]3 years ago
5 0

Answer:

3 units

Step-by-step explanation:

By intersecting chords theorem:

AE \times EB = CE \times ED

\therefore 3 \times 4= x \times (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\neq - 4

\implies x = 3

\implies CE = 3
