The sailboat in Question #1 returns to port in a straight line from its current position. The captain would like to know the total distance traveled (refer to distances in question #1).

1. What was the total distance traveled?
2. What was the final displacement?

1. 5.3+2.5+5.86= 13.66km

2.would i double 13.66?

Not knowing the path, it is impossible for me to add anything.
oh wow im sorry! :)

A sailboat sails west from port for 5.3 km and experiences a shift in the wind direction. The wind blows the sailboat 2.5 km south. What is its displacement from its original position?

a^2+b^2=c^2
5.3^2+2.5^2=5.86^2SW
displacement= sqrt(5.3^2+2.5^2)

Now, the angle: Tan Theta= 2.5/5.3

so Theta = arctan(2.5/5.3) S of W
what is theta and arctan?!
