Final answer:
The signs for each vector are negative, negative.
Step-by-step explanation:
The sign for each vector can be determined by analyzing the given information:
Vector A has a magnitude of 122 cm and an angle of 145 degrees. Since the angle is in the second quadrant, the x-component is negative, making the sign of A negative.
Vector B has a magnitude of 110 cm and an angle of 270 degrees. Since the angle is along the negative y-axis, the y-component is negative, making the sign of B negative.
Therefore, the signs for each vector are:
A) Negative, Negative
B) Negative, Negative
C) Negative, Negative
D) Negative, Negative
