Question

Find the value of x to the nearest tenth

Answer 1

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

Answer 2

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:

$\frac{2x}{62}=\frac{39}{39+39}$

$\frac{2x}{62}=\frac{39}{78}$

$\frac{x}{31}=\frac{39}{78}$

$\frac{x}{31}*31=\frac{39}{78}*31$

$x=\frac{1}{2}*31$

$x=15.5$

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