Answer:
[tex]x=13[/tex]
Explanation:
From the question we are told that
Magnitude 1 [tex]M_1=5[/tex]
Magnitude 1 [tex]M_2=12[/tex]
Generally the Pythagoras equation for the magnitudes is mathematically given as
[tex]\sqrt{x^2}=\sqrt{M_1^2 +M_2^2}[/tex]
[tex]\sqrt{x^2}=\sqrt{5^2 +12^2}[/tex]
[tex]x=13[/tex]
Therefore resultant magnitude is
[tex]x=13[/tex]
