Answer:
[tex]r_x=-175\sqrt{3}mph[/tex]
[tex]r_y=-175mph[/tex]
Step-by-step explanation:
we are given
A jet is flying at 350 miles/hour in still air
so, we get
[tex]|r|=350[/tex]
It is traveling in the direction of 210°
so, we get
[tex]\theta=210[/tex]
now, we can use component formula
[tex]r_x=|r|cos(\theta)[/tex]
now, we can plug values
[tex]r_x=350cos(210)[/tex]
[tex]r_x=-175\sqrt{3}mph[/tex]
[tex]r_y=|r|sin(\theta)[/tex]
now, we can plug values
[tex]r_y=350sin(210)[/tex]
[tex]r_y=-175mph[/tex]
