Respuesta :
An equilateral triangle have all its three sides to be congruent.
The value of x is 4
From the question (see attachment), we have the following observations.
- MN is one of the side lengths of the original equilateral triangle.
- MR is half the length of MN
Given that:
[tex]\mathbf{MN = 8}[/tex]
Side length MR is then calculated as:
[tex]\mathbf{MR = \frac 12 \times MN}[/tex]
So, we have:
[tex]\mathbf{MR = \frac 12 \times 8}[/tex]
[tex]\mathbf{MR = 4}[/tex]
Also:
[tex]\mathbf{MR = x}[/tex]
So, we have:
[tex]\mathbf{x = 4}[/tex]
Hence, the value of x is 4
