One afternoon, a couple walks two-thirds of the way around a circular lake, the radius of which is 1.60 km. They start at the west side of the lake and head due south to begin with.(adsbygoogle = window.adsbygoogle || []).push({});

What are the magnitude and direction (relative to due east) of the couple's displacement?

For the direction, is the answer found by using this: (2/3)(360 degrees) - 180?

How would I find the magnitude?
