So I think I know how to do this but tell me if I’m wrong so, 2x+45 and then it’s verticals angle is the same thing so it’s the same, then it’s same side with x so it’s whatever 2x+45 is solved? If I’m wrong then please explain how to do this

So I think I know how to do this but tell me if Im wrong so 2x45 and then its verticals angle is the same thing so its the same then its same side with x so its class=

Respuesta :

Since the two lines in the figure are parallel, due to interior angles theorem, it follows:

[tex]\begin{gathered} x+2x+45=180 \\ 3x=180-45 \\ 3x=135 \\ x=\frac{135}{3} \\ x=45 \end{gathered}[/tex]

So the value of x is 45.
