The displacement vector A(vector) has scalar components of A_x = 80.0 m and A_y = 60.0 m. The displacement vector B(vector) has a scalar component of B_x = 60.0 m and a magnitude of B = 75.0m. The displacement vector C(vector) has a magnitude of C = 100.0 m and is directed at an angle of 36.9^o above the + x axis. Two of these vectors are equal. Determine which two, and support your choice with a calculation?
