Vector A points in the negative direction. Vector B points at an angle of 35.0 above the positive x axis. Vector has a magnitude of 10 and points in a direction 46.0 below the positive x axis.
Also: Given that A+B+C=0, find the magnitudes of A and B.

To understand the given vectors and their directions, we can use the concept of vector representation and vector components.
1. Vector A points in the negative direction: This means that Vector A points in the opposite direction of the positive x-axis.
2. Vector B points at an angle of 35.0° above the positive x-axis: To represent Vector B, we need to use its magnitude and its direction angle. The direction angle is measured from the positive x-axis in a counterclockwise direction. So, we can represent Vector B as B = B magnitude * cos(35.0°) i + B magnitude * sin(35.0°) j, where i and j represent the unit vectors along the x-axis and y-axis, respectively.
3. Vector C has a magnitude of 10 and points in a direction 46.0° below the positive x-axis: Similar to Vector B, we can represent Vector C using its magnitude and direction angle. Since it points below the positive x-axis, the angle will be measured in the clockwise direction. So, Vector C can be represented as C = C magnitude * cos(-46.0°) i + C magnitude * sin(-46.0°) j.
Note: The negative sign with the angle indicates the opposite direction.
By using the above representations, we can calculate the components of vectors B and C.
Component of Vector B:
- Bx = B magnitude * cos(35.0°)
- By = B magnitude * sin(35.0°)
Component of Vector C:
- Cx = C magnitude * cos(-46.0°)
- Cy = C magnitude * sin(-46.0°)
Once we have the vector components, we can work with them for any further calculations or analysis.
