Answer: 72
Step-by-step explanation:
The sum of exterior angles of a triangle is equal to 360º.
For the given triangle:
[tex]2x[/tex]°+[tex]2x[/tex]°[tex]+x[/tex]° = 360
Solve x in the equation above:
[tex]5x=360[/tex]
Divide both sides of the equation into 5:
[tex]\frac{5}{5}x=\frac{360}{5}[/tex]
x=72
Then, the value of x is 72
