    Subtracting Vectors: How to Find Magnitude of A-B

    This is the problem that I was given: Given two vectors A and B, with magnitudes |A| = 45.7 and |B|=38.2 and directions (from the x-axis) θA=64° and θB=145°, find the magnitude of (A-B) I know that this somehow involves triangles and trigonometry, but I am really confused as to how I do...
