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 is 0.60 because the sum of the shaded angles equals 145°, divided by 360° equals 0.60
Here is the answer to the equation. The photo below is the work shown.
