Answer:
[tex]UV = 2[/tex]
Step-by-step explanation:
Given
[tex]UW = 13[/tex]
[tex]VW = 11[/tex]
Required
Determine UV
From the question, we have
[tex]UW = UV + VW[/tex]
Make UV the subject of formula
[tex]UV = UW - VW[/tex]
Substitute 11 and 13 for VW and UW, respectively
[tex]UV = 13 - 11[/tex]
[tex]UV = 2[/tex]
