Does anyone know this ??

x=52

Step-by-step explanation:

vertical angles are congruent so that means the angle measures are the same

so, you can set up this equation:

156=3x

and solve as follows:

156=3x

/3     /3

52=x

To prove that x=52 you can input 52 as x in the equation

156=3(52)

156=156

:) I hope this helps :)
