Answer: 
6 centimeters.
Step-by-step explanation: 
For chords that intersect inside a circle, we have the intersecting chords theorem, which states that the product of both colinear segments are equal to the products of the intersecting colinear segments meaning that:
So 12*4=8*x
We just have to clear x from the equation to get the value of X:
So the segment Y measures 6 cm.
 
                                
             
                    
              
we know that
<u>The intersecting chords theorem</u> states that the products of the lengths of the line segments on each chord are equal
so
in this problem
we have
substitute the values
therefore
<u>the answer is </u>

So hmm notice the picture below
you have the center, and a point on the circle... all you need is the radius
then use that radius in the circle's equation

Part A: 6w + 12 = 5w + 15
        
             
        
        
        
Answer: 
B
Step-by-step explanation: 
All we have to do is plug in the values! 1/2(4)(10+5) will give us the area. Now we simplify!
2(15) = A
30=A
Our answer is B!
 
        
             
        
        
        
The equation is like this 5×3 + 4×6 = 39
