2) A is 8.5cm long and pointed to the right (+x axis). B is 6.0cm long and pointed up and to the left, at 120° counter-clockwise from +x. Draw the two vectors and use graphical methods to find the magnitude and angle-from-+x of C where A+B=C. Make sure your submission is scanned without warping, so the angles can be checked.

Magnitude

A vector is an element with both direction and magnitude. A vector is represented using an arrow, where the arrow represents the direction of the vector and its length is represented using the magnitude. The set of vectors in space is known as vector space. The vectors can be added, subtracted, multiplied, and divided in a vector space. The image below shows a vector AB.
