The angle whose measure is 60° and the angle (2x)° are vertical angles, if two angles are vertical angles, then they are congruent, then we can express:
[tex]2x=60[/tex]
From this expression, we can solve for x to get:
[tex]\begin{gathered} \frac{2x}{2}=\frac{60}{2} \\ x=30 \end{gathered}[/tex]
Then, x equals 30
