A vector is located in the x-y plane. The x and y components of this vector are 4.00 m and 3.00 m, respectively. Find the angle
that this vector makes with the positive y-axis.

Answer:
Step-by-step explanation:
Consider vector A as shown in the figure given. The x- and y-component of vectors are given as Ax and Ay.
The angle of the vector with positive x-axis is given by,
∅ = (
)
= (
)
=
Where: Ax = x-component of the vector ann Ay=x-component of the vector
Thus, the angle of vector:
α = 90-∅
=

Step-by-step explanation:
Cosine is the adjacent side over the hypotenuse (You can remember sin, cos, and tan by using sohcahtoa or sin = opposite/hypotenuse, cos = adjacent/hypotenuse, tan = opposite over adjacent). I think a picture would help, too.
I attached a picture of what I think the triangle would look like.
If the picture is right (we're assuming it is) and going with what we're given (the triangle was addressed as triangle XYZ, meaning that <u>angle Y is in the middle and that's the one we'll use</u>).
Looking at my picture then:
