Answer:
b
Step-by-step explanation:
 
        
             
        
        
        
The segment length is 14 (square root)2 
Given that Triangle ABC is right angle triangle
The vertex marked is B where side AC is the hypotenuse
The side of AC is at Vertex B is 14 
The dash segment from vertex B to point D on side AC
Angle BDA is marked right angle .
 Angles A and C both marked 45 degrees.
As shown in diagram 
Triangle ABC is drawn according to the statement where B is vertex 
The side lengths are 14  
Now to find Another side length that is x
So , the equation formed is 
x*cos45 = 14
x/√2 = 14
x = 14√2
Hence the length of the segment is 14√2
