The length of the unknown leg of the triangle is 15 m. 
<u>Step-by-step explanation:</u>
Length of one leg = 20 m
Length of the hypotenuse= 25m
As it is a right angled triangle we can use pythogoras theorem. 
Let the unknown length be y
(20) (20)  + y(y) = (25) (25) 
400 + y(y) = 625
y(y) = 225
y = √225
y = 15 
The length of the unknown leg is 15 m. 
 
        
                    
             
        
        
        
Answer:
The length of mid-segment 
 units
Step-by-step explanation:
Given:
Length of 
 units
 is the mid-segment which means the line joining the midpoints of two sides of triangle.
By mid-segment theorem the mid-segment of a triangle is parallel to the third side and half of the length of third side.
So, we can write:
  
 
∴ 
 units
∴The length of mid-segment 
 units
