    Answer: ||\vec A|| \approx 9.95 m,||\vec B|| \approx 8.19 m

    Explanation:

    Magnitudes can be calculated by using Pythagorean theorem:

    ||\vec A|| =\sqrt{(5m)^{2}+(-7m)^{2}+(5m)^{2}}\\||\vec A|| \approx 9.95 m\\||\vec B|| =\sqrt{(3m)^{2}+(7m)^{2}+(-3m)^{2}}\\||\vec B|| \approx 8.19 m\\
