First, lets look at the coordinates of the tip. The x-coordinate is 12cos 80, and the y-coordinate is 12sin 80. Now use unit vectors to write:(12cos80)i + (12sin80)j

The unit vector is
cos(80) i + sin(80) j

Another homework question.
x=12cos(80)i
y=12sin(80)j
R=12cos(80)i+12sin(80)j

x = cos(80) * 12
y = sin(80) *12
vextore = x(xdirection)+ y(ydirection)
