I can't edit pictures for you so as a result I can't answer it. But label those  numbers on the x line and that will be your answer. And OMG your laptop is torn up I tell you TORN.
 
        
             
        
        
        
Answer:  Length of AB is 16 cm 
Step-by-step explanation:
Given: Diameter of a circle is 20 cm and CE = 4 cm
Now as shown in figure AO, BO, CO are radii 

Therefore 
AO=BO=CO= 10 cm
Now 

Now in Δ OEB 
∠OEB =90°
Therefore by Pythagoras theorem : In a right angle triangle the square of hypotenuse is equal to the sum of square of other two sides.
So we have

Now as we know perpendicular to the chord from the center of a circle bisect the chord.
Therefore

Hence , the  length of AB is 16 cm .
