Suppose that $||vec(v)||=16$ and $||vec(w)||=6.$ Suppose also that, when drawn starting at the same point, vec$(v)$ and vec$(w)$ make an angle of $\frac{5}{6}$ radians.

$($A$.)$ Find $||vec(w)+$vec$(v)||$ and round to two decimal places.

$||vec(w)+$vec$(v)||=$

$($B$.)$ Find $||vec(w)-$vec$(v)||$ and round to two decimal places.

$||vec(w)-$vec$(v)||=$
