hint Hint:

magnitude of vector= $square root of a squared plus b squared end root$
tanθ= $a over b$

The correct answer is: 10,53

To find the magnitude or length of a vector, take the square root of the sum of the squares of each component $square root of a squared plus b squared end root$

Given the vector $v = 6 i -8 j$ (equivalent to $< 6, -8 >$ )

$square root of 6 squared plus left parenthesis negative 8 right parenthesis squared end root$

To find the direction
$a over b$ $a over b$
