Answer:
x=2.2
Step-by-step explanation:
You know that for triangle ABC, side AB=10, CB=2 and AD=AB+BD=10+1=11. Given that triangles ABC and AED have the same angles, they are similar triangles.
So we can use the following ratios to solve for ED=x:
f = 16
2 = f/8
Cross Multiplying, we get

12
Where
Substituting the values
f( x ) = - 1/3 x + 5
