Explanation:
+ B = 6,123 units at angle 112,5 degrees.
A - B = 14,782 units at angle 22,5 degrees.
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.
