Vectors in each direction should equal to each other. For the second part, the two vectors are parallel if they are multiples of each other. I will upload 3rd part soon.

Use area of vector triangle = 1/2 |one of the sides||the other side| sin(angle), take note that i could cancel sin(angle) and sin(180-angle) out because sin(angle) = sin(180-angle) -> this is under the trigo rules
