Answer:

  • 39 km due south

Step-by-step explanation:

Since the two vector have opposite directions, their sum will be the difference of magnitudes:

  • r + s = 164 - 125 = 39

And the direction is the same with the vector with greater magnitude, so it is south.

Answer:

Magnitude = 39 km

Direction = South

Step-by-step explanation:

Formula we use,

→ r + s

Now the required answer will be,

→ r + s

→ 164 + (-125)

→ 164 - 125

→ 39 km

Thus, answer is 39 km due south.
