SUMMARY

The discussion focuses on solving vector problems using graphical methods, specifically for force vectors FA and FB. FA has a magnitude of 90.0 Newtons due east, while FB has a magnitude of 135 Newtons at 75° north of east. Participants clarify that to find the resultant vector FA - FB and FB + FA, one must draw vector diagrams and apply the cosine and sine formulas. The correct answers for the magnitudes and directions are 142 N and 67° north of east for FB + FA, and the method involves using the component method and Pythagorean theorem for accurate calculations.

Hi guys...
I am new to his website and i don't know if i am using the correct place to ask my question:shy:
Well the question is:
When a vector is given say A: a i^+b j^+ck^ then how to find the angle between the vector and x-axis: y- axis; z-axis
Thanq for ur time ...
