three vectos are shown in fig. 332. their magnitudes are given in arbitrary units. Determine the sum of the three vectors. Give the resultant in terms of (a) components, (b) magnitude and angle with the x axis.
(332 the figure has three rays all starting at the origin. Ray A = 44.0 and is 28degress from the x axis in quodrent 1. Ray B=26.5 and is 56degress from the x axis in quodrent 2. Ray C=31.0 and is on the y axis between quodrent 3 and 4.)

break up all three vectors into x,y components. then add the x's, and the y's.
That is the resultant vector. 
a)4
b)4
C)3 
A0
