Answer 1

Answer #1

If both A_x > 0 and A_y > 0, it means the vector lies in the 1^st quadrant.

And any vector lying in the first quadrant makes 0^o to 90^o with the positive x-axis

2nd quadrant 1st quadrant 0-90 degrees 3rd quadrant 4th quadrant

I hope i was able to answer your question. If you need anymore explanation, please ask in comments. I would be happy to help.
