Answer:
The magnitude of the vector addition is approximately 10.38
Explanation:
Recall that the vectors add easily in component form, just by adding component by component:
A = (6.7, -2.3)
B = (-5.5, 4.5)
C = (3.2, 7.2)
A + B + C = (6.7- 5.5 + 3.2, -2.3 + 4.5 + 7.2 ) = (4.4, 9.4)
Then, this vector's magnitude is calculated via:
[tex]\sqrt{4.4^2+9.4^2} \approx 10.38[/tex]
