# Vector 7

Given vector OA(12,16) and vector OB(4,1). Find vector AB and vector |A|.

Correct result:

x =  -8
y =  -15
A =  17

#### Solution:

$x=4-12=-8$
$y=1-16=-15$
$A=\sqrt{ x^2+y^2 }=\sqrt{ (-8)^2+(-15)^2 }=17$ We would be pleased if you find an error in the word problem, spelling mistakes, or inaccuracies and send it to us. Thank you! Tips to related online calculators
