The expression that represents the value of s is s = 1/2u
How to determine the expression represents the value of s?
From the question, we have the following parameters that can be used in our computation:
The triangle
Given that
E is the midpoint of point AC and point D is the midpoint of BC
Then
s = 1/2 * u
Evaluate
s = 1/2u
Hence, the expression represents the value of s is s = 1/2u
