What is the $x-$component of vector vec$(r)$ from the starting point $($position $O)$ to the city $C?$

Answer in units of $km.$

A commuter airplane starts from an airport located at the origin. First it flies to city A located $110km$ away from the airport in a direction $26$ North of East. Next it flies $60\mathrm{.}5km$ at $40$ West of North to city B$.$ Finally it flies $188km$ due West to city C$.$

What is the $x-$component of the vector vec$(b)?$ Consider $E$ to be the positive $x$ axis and $N$ to be the positive $y$ axis.

$b_x=-$bsin$$

$b_x=$bsin$$

$b_x=$btan$$

$b_x=$bcos$$

$b_x=-$btan$$

$b_x=-$bcos$$
