YO HELP A SISTER OUT I NEED IT!!!!!!!!!!

Answer 1

Answer:

the ans is 7

Step-by-step explanation:

given CE=12 and DC=5

therefore DE=CE-DC

=12-5

=7

now DE and AB are equal as they are the diameters.They are drawn from the surface of the circle.

thats why the value of AB is 7

now value of BC is 6

therefore the value of AC is AB+BC=7+6

=13

hope it helps u mate

Answer 2

In the circle,by formula for secants

ACxBC=ECxDC

ACx6=12x5

AC=60/6

AC=10
