Explanation:
To solve this problem we will decompose each of the directions in the x & y axes.
To solve this problem we will decompose each of the directions in the x & y axes. also for a greater understanding of the angles, you should look at the attached image, which contains the orientations for each angle (clockwise or counterclockwise).
<u>59.0 km in a direction 30.0° east of north</u>
<u />
<u>58.0 km due south</u>
<u />
<u>It flies 100 km 30.0° north of west</u>
<u />
<u /><u />
<u />
Now we sum algebraically the components
Using the Pythagorean theorem we can find the magnitude of the displacement.
