Answer 1

Explanation:

For vector addition, we resolve each vector into horizontal and vertical components and then add each direction separately.

The overall magnitude is ten found from Pythagoras, and the direction from a trig ratio. (Details in sketch)

For vector subtraction, simply add the negative of the second vector and repeat the process.
