I need help with this question. I have the vector magnitudes correct, however my angles are wrong. I am not sure what I am doing wrong. I used the inverse tangent of theta to find the angles (theta=tan^-1(Ay/Ax). However, I am still getting the wrong angles. The questions are in the images below;

Each of the following vectors is given in terms of its x- and ycomponents. Find the magnitude of vector 2 and the angle 0A it makes with respect to the positive x-axis, measured counterclockwise, when Ax = 2.00 and Ay = 4.00. A = 4.47 63 Incorrect Find the magnitude of vector 3 and the angle 03 it makes with respect to the positive x-axis, measured counterclockwise, when Bx = 3.00 and By = 3.00. B = 4.24 45 Incorrect Find the magnitude of vector C and the angle Oc it makes with respect to the positive x-axis, measured counterclockwise, when Cx = 0.00 and Cy = -2.00. C = 2.00 0 0c = Incorrect
