Question

find the horizontal and vertical component of the vector with given length and direction, and write the vector in terms of i and j:
v= 50, theta= 120*

Answer 1

in your case, you have right triangle with (v) hypotenuse = 50, and angle = 120,
and the legs are i and j, you can easily find them ,using simple trigonometry formulas.

Answer 2

ops, actually your angle will be 60,
and remember your vector is in the left upper side of the plane

Answer 3

you are in the second quadrant of the xy plane so i will be -(cos(60)*50)=-25 and j will be +(sin(60)*50)=+43.30
