Physics: Vectors; Given the Vectors A and B [Solved]

-75.94*i 4.72*j The vector is in the 2nd quadrant

Vector A = 61*cos28*i 61*sin28*j
Vector B = -40*cos56.5*i 40*sin56.6*j

Vector A = 53.86*i 28.64*j
Vector B = -22.08*i 33.36*j

75.94*i 4.72*j the vector is in the 4th quadrant

-75.94*i 4.72*j The vector is in the 2nd quadrant

Magnitude [75.94 4.72] = 76.1
Angle = 93.6 [arctan(4.72/75.94) in the 2nd quadrant]

75.94*i 4.72*j the vector is in the 4th quadrant

A B is simply the negative of B A

Magnitude is the same = 76.1
Angle = 274 [arctan(4.72/75.94) in the 4th quadrant]

I found it hard to read the length of vector B; it looks like 40.

If the two vectors A
