Given:
Two vectors (u) and (w) and the angle between them θ

the sketch of the vectors will be as shown in the following figure:
As shown, the resultant vector is the blue line segment
The vector R has a magnitude = 60.22
And the angle between u and R = 5.56°
The answer to 14+(-2) is 12
900 because you have to add 24 squared + 18 squared
