Answer:
15.5
Step-by-step explanation:
We have been given a diagram. We are asked to find the value of x.
Upon looking at our given diagram, we can see that both triangles are similar.
We will use proportion to solve for x as:
[tex]\frac{2x}{62}=\frac{39}{39+39}[/tex]
[tex]\frac{2x}{62}=\frac{39}{78}[/tex]
[tex]\frac{x}{31}=\frac{39}{78}[/tex]
[tex]\frac{x}{31}*31=\frac{39}{78}*31[/tex]
[tex]x=\frac{1}{2}*31[/tex]
[tex]x=15.5[/tex]
Therefore, the value of x is 15.5 for our given diagram.
