4. my final answers are:
329.42, 412.42
i did: 469.84+(-141.42)=329.42
i did: 171.01+141.42 = 412.42

5. first of all, I got
(328.42 , 312.43) as the resultant vector, still not done

NOW, find the magnitude and direction of that.

8. tanø = rise/run = 312.43/328.42
ø = tan^-1 (.95130..)
= 43.57°

btw, your magnitude is wrong
magn = √(328.42^2 + 312.43^2) = 453.29
