the answer to this question is 85. first solve the problem, then use conplete sentences, at least 5 sentences to describe the steps involved in solving the problem. What theorem did you use?

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
