# Given 2 vectors A = 4.00i + 3.00j  and B =5.00i - 2.00 j how do you find the magnitude of each vector?

Feb 23, 2016

magnitude of vec $A = 5$
and magnitude of vec $B = 5.385$

#### Explanation:

Magnitude of a vector is determined by sqrt(a^2+b^2+c^2...
so,

|vec A|= sqrt(4^2+3^2 = 5

and

$| \vec{B} | = \sqrt{{5}^{2} - {\left(- 2\right)}^{2}} = 5.385$
