We will assume that the question is referring to the angles of a triangle. The vertices are 2x, 40, and 60.
Then, we have that the internal angles of a triangle sum up to 180 (degrees). Then, we have:
[tex]2x+40+60=180[/tex]
Then, we have that subtracting 100 to both sides of the equation:
[tex]2x+100=180\Rightarrow2x+100-100=180-100\Rightarrow2x=180-100[/tex]
Dividing by 2 to both sides of the equation:
[tex]\frac{2x}{2}=\frac{80}{2}\Rightarrow x=40[/tex]
Therefore, we have:
[tex]2\cdot40+40+60=180[/tex]
Therefore, the value for x is equal to 40 (x = 40).
