Is this your problem - or you are trying to help somebody-else?

If it is somebody-else's problem - it will be useful if that somebody directly contacted us, showing work done upto now.

Please have your son come to the site directly. If you want to follow along, you can look over his shoulder. We have found that trying to explain something through a third party is almost impossible. The way we work is that we give help, not answers, so we need to find out what your son is thinking, where he is blocked, what math facts he already knows, etc.

I tutor in person a girl whose father is an engineer well versed in math. Even he has found that cannot tutor his child because he is not used to finding out what is confusing to her when it seems so obvious to him. (In fact, I suspect he knows more math than I do, but still ...)

Corresponding angles with parallel lines.
Therefore, \(\displaystyle x=3x-70\) so \(\displaystyle x=35\). A is the supplement angle.
