# How do you find the magnitude of the resultant of the vectors A=12x-37y+52z and B=5x+30y-42z. where i, j, and k are unit vectors along the x, y and z axes respectively?

The resultant is A + B = ( 12, -37, 52 )-( 5, 30, -42 = ( 17, -7, 10 )
Magnitude = $\sqrt{438}$
Magnitude of ( x, y, z ) = $\sqrt{{x}^{2} + {y}^{2} + {z}^{2}}$
