Answer:AC=BD=2cm
Step-by-step explanation:now since in the circle OZ perpendicularly bisects BC and AD(. BECUSE it is distance form the circle bisexts the chord)
Hence- ZC=ZB=1/2 OF 8 = 4 CM. - i
AZ=DZ= 1/2 OF 12 = 6cm. - ii
NOW subtracting ii from i
= AZ-CZ=DZ-VS=(6-4)cm
=AC=BD=2cm
Hence = AC=BD= 2cm
use the picture I made to avoid confusion :)
