Question

A person walks 25.0° north of east for 3.10 km. How far due
north and how far due east would she have to walk to arrive at
the same location?​

Answer 1

Explanation:

Use sine and cosine to find the vertical and horizontal components.

31.0 km × sin 25.0° = 13.1 km north

31.0 km × cos 25.0° = 28.1 km east

She would have to walk 13.1 km north and 28.1 km east.
