How Do You Calculate Vector Components and Resultant Displacement?

[hizeme]

Homework Statement

1. A displacement vector has a magnitude of 810m and points at an angle of 18 degrees above the positive x axis, What are the x and y scalar components of this vector?

2. A displacement vector is 23 km in length and directed 65 degrees south of east
What are the components of this vector (East=x South =y)

3. Four members of the Main Street bicycle club meet at a certain intersection on Main Street. The member then start from the same location, but travel in different direction. A short time later, displacement vectors for the four members are:
A=2.0km east B=5.2km north C= 4.9km west D=3.0kmsouth
What is the resultant displacement R for all the members of the bicycle club
r=a+b+c+d
