Answer:

15.5

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:


(2x)/(62)=(39)/(39+39)


(2x)/(62)=(39)/(78)


(x)/(31)=(39)/(78)


(x)/(31)*31=(39)/(78)*31


x=(1)/(2)*31


x=15.5

Therefore, the value of x is 15.5 for our given diagram.
