Respuesta :

Angle 1 and Angle 2 are vertical angles.

Vertical Angles are equal.

So, we can write:

[tex]x+50=3x-20[/tex]

Lets solve this:

[tex]\begin{gathered} 3x-x=50+20 \\ 2x=70 \\ x=\frac{70}{2} \\ x=35 \end{gathered}[/tex]

Angle A:

x + 50

x is 35, so

35 + 50 = 85

Angle A is 85 degrees
