theta=arcTan(7.2/5.7) and since it is in the third quadrant,
theta=arctan(7.2/5.7) + 180 degrees
Consider the vector v=-5.7i-7.2j
Approximate to the nearest tenth of degree the angle vector v makes with the positive horizontal direction?

Thanks for the help! I wanted to ask how did you know that we're supposed to divide (7.2/5.7) and not the other way around?
if the angle A is drawn in the standard position, tan(A) = y/x
