Question

Find the value of x to the nearest tenth

Answer 1

2x = 62/2 = 31
x = 31/2 = 15,5

Answer 2

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.
