comment Measurement of angle of vectors gives strange result…
Thank you Sir. What a silly mistake I made. Now, with the correct value of the director, I have been able to successfully complete the rest of steps in a proper way. That little detail was the only thing blocking me of doing it right.

Of course, sorry if I have been a bit confusing. I have just edited the initial post.

final edit: Yes, I checked again, and a segment where A=(150,50) and B=(550,350), seems perpendicular to another where A=(150,50) and B=(-35,55)... and (-185,5) is the director of this last segmento... whereas (300,300) is the director of the first one.

Thanks, that's what I was doing, but in the last step of solving for x, I ran into the square root of a negative number. That's what stopped me from continuing...

comment Parameterize a straight line using polar coordinates… without angle.
Thanks, your example made it look much easier than in my textbook. What a fascinating subject!
