Question

2. The components of vector X are given as follows:
Ax = 5.6 Ay = -4.7
What is the angle between vector A and positive direction of x-axis?
A. 320° B. 180° C. 90
D. 127
E. 230°​

Answer 1

Answer:

Apply the equation. to find the magnitude, which is 8.6.

Apply the equation. to find the magnitude, which is 8.6.Apply the equation theta = tan–1(y/x) to find the angle: tan–1(–7.0/–5.0) = 54 degrees. However, note that the angle must really be between 180 degrees and 270 degrees because both vector components are negative.
