Difficult Vector Questions?

I'm having trouble with these problems..matter of fact I don't even know where to start..please help thanks.

1. Find the distance of the point http://webwork2.math.utah.edu/webwor...6285fe0e61.png from the line through http://webwork2.math.utah.edu/webwor...f549632471.png which points in the direction of http://webwork2.math.utah.edu/webwor...02de190301.png.

2. Find the vector http://webwork2.math.utah.edu/webwor...c04c09b3d1.png which makes an angle of 60 degrees with the vector http://webwork2.math.utah.edu/webwor...1cc8421d41.png and which is of the same length as http://webwork2.math.utah.edu/webwor...e5b96d4b01.png, and is counterclockwise to http://webwork2.math.utah.edu/webwor...d042f6c3a1.png.

3. You start walking from a point with coordinates (1, 1) and arrived at the point with coordinates (2, 5). If you began walking in the direction of the vector http://webwork2.math.utah.edu/webwor...b341d3b261.png and you change direction only once, when you make a turn at a right angle, what are the coordinates of the point where you make the turn?

I figured out 2 and 3 already. I still need help on 1. Thanks
