lets set up a coordinate system, angles based on x axis, measured counterclockwise.

A=11.4*cos48.4 x + 11.4*sin48.4 y

C=14.8*cos196.6 x + 14.8*sin196.6 y
A-C=(11.4*cos48.4-14.8*cos196.6 )x +(11.4*sin48.4-14.8*sin196.6)y
= (11.4*.664-14.8*-.999 )x +(11.4*.748-14.8*-.286)y
= 22.4 x +12.8 y
Well, I get a much different magnitude, and the angle arc tan(12.8/22.4)=29.7deg
so check the above, and recheck your work.
In the sum A+B+=C, vector A has a magnitude of 11.4 m and is angled 48.4 degrees counterclockwise from the +x direction, and vector C has a magnitude of 14.8 m and is angled 16.6 degrees counterclockwise from the -x-direction. What are the A) magnitude and B) the angle (relative to +x) of B? state your angle as a positive number. I know it is A-C=B but I have the wrong answer please help and explain if you can. my incorrect answers are 8m and 33 degrees
