Question

What is the value of x in the figure at the right? 60° (2x)°

Answer 1

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:

`2x=60`

From this expression, we can solve for x to get:

`\begin{gathered} (2x)/(2)=(60)/(2) \\ x=30 \end{gathered}`

Then, x equals 30
