can you explain and work out the following problem?

Question

Consider a vector of 2.8 m/s due south along y axis, and a vector of 4 m/s pointed 21 degrees north of east along X axis. Add the vectors. What is the resulting vectors magnitude and direction? (separate into components..add components stay on point with sig fig)

Answer 1

Draw and label a diagram.

Translate tail of south vector to tip of east vector.

This forms a 69° angle.

Use Law of Sine to determine angle and magnitude of resultant.
