Answer:

d=  20

Step-by-step explanation:

1. Equation for finding length segment:

d=  √ (x1 - x2)2 + (y1 - y2)2  

2. Find the values

Let (x1, y1) = (11,10)

Let (x2, y2) = (-9, 10)

3. Substitute

d=  √ (11- -9)2 + (10 - 10)2  

d=  √ (20)2 + (0)2  

d=  √ (400) + (0)  

d=  √ (400)

d=  20

Hope this helped :)
