An object is located at the point (−3.00m,4.00m,0.00m). A position vector connects this object to the origin. Find the magnitude of the position vector and the angle it makes with the positive x-axis.
I know the magnitude is 5.00m, how do I find the angle?

it has no z componet,so the angle is in the xy plane, arctan4/(-3) in second quadrant -53deg about, or about 307 deg
what would that be in radians? Is it 2.42?
