Answer:

4 units

Step-by-step explanation:

see attachment for the missing figure.

to find the value of AY or x

We'll use intersecting chord theorem i.e the product of line segment of each chord are equal.

From the figure, we can say that:

BY x YD = AY x YC

$BY \times YD = AY \times YC\\3\times 8=x\times 6\\24=6x\\x=\frac{24}{6}\\x=4$

Therefore, AY = 4 units
