Parallelogram Law of Vector Addition
When two vectors are represented as adjacent sides of a parallelogram, the resultant vector is given by the diagonal of the parallelogram.
R = √(A² + B² + 2ABcosθ)
The direction of the resultant vector can be found using the sine rule:
R/sinθ = A/sinβ = B/sinα
Resultant Magnitude (R):
8.66 units
(7.50, 4.33, 0.00)
Angle between A and R (α):
30.00°
