## Homework Statement

For the vectors vector A and vector B in the figure below, use a scale drawing to find the magnitude and direction of the following vector operations. (A = 12.4 m, and B = 18.6 m.)

(Measure angles counterclockwise from the +x axis) Visual link below

I was digging a little online and I found another guy with the same problem. He even has the same questions I am stuck on.

The only thing different are the numbers I have which are stated above. Someone replied with the answer but I have no idea how he got them.

## Homework Equations

The only ones I have been given are A+ B = The square root of a^2 + b^2

I also have that Tan(theta) = (ay/ax)

## The Attempt at a Solution

I got a correct (both the magnitude and angle). However on b I cannot get the angle correct. C and D I am on now. If any help could be provided that would be great. Moreso is how you set up the equations =) I care more on that than the actual answer.
