checking vector work

[Dorian Gray]

Greetings Fellow Mathematicians,

I was wondering if somebody could please check my work for the following vector problem. I had a 11.46 for my resulting vector and an angle of 13.83 degrees. I have no key for this problem, and our professor said we will have a problem like this on our exam, so I definitely want to make sure I understand it well.


Thank you for your comments, help, tips, suggestions, etc....

I caught an error. the Angle should be 310 degrees and not 320 degrees for the last one.
