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({});

(a) What is the distance they travel?

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

i know that the distance is 6.702 km, but I dont know how to find the magnitude and the direction. I know that whatever the direction is, it is north of west.

Can you help me figure out the magnitude and the direction? please!!
