Answer:
![ED=32\ units](https://tex.z-dn.net/?f=ED%3D32%5C%20units)
Step-by-step explanation:
we know that
Applying the Intersecting Secant Theorem
![AC*BC=EC*DC](https://tex.z-dn.net/?f=AC%2ABC%3DEC%2ADC)
substitute the values
![(16+5)*(5)=(ED+3)*(3)](https://tex.z-dn.net/?f=%2816%2B5%29%2A%285%29%3D%28ED%2B3%29%2A%283%29)
Solve for ED
![(21)*(5)=(ED+3)*(3)](https://tex.z-dn.net/?f=%2821%29%2A%285%29%3D%28ED%2B3%29%2A%283%29)
![35=(ED+3)](https://tex.z-dn.net/?f=35%3D%28ED%2B3%29)
![ED=35-3=32\ units](https://tex.z-dn.net/?f=ED%3D35-3%3D32%5C%20units)
