![### Vector Geometry Problem
Consider the cuboid shown in the figure. The lengths of the edges [KL], [LM], and [LX] are 8 units, 5 units, and 3 units, respectively. Point P is identified as the midpoint of the edge [KL]. Using vector methods, determine the measure of the following angles:
#### Given:
- KL = 8 units
- LM = 5 units
- LX = 3 units
- P is the midpoint of KL.
#### Questions:
a. Measure of angle \( \angle YNX \)
b. Measure of angle \( \angle YNP \)
### Diagram Description:
The diagram shows a cuboid labeled with vertices W, X, Y, Z, K, L, M, and N.
- K, L, P, and M are in the lower base with K and L on the horizontal axis.
- W, X, Y, and Z are vertices on the upper base.
- K and W, L and M, and X and Z are vertically aligned.
- P is marked as the midpoint of the line segment KL. A dotted diagonal line connects L and W as well as the line segments of the upper base, forming additional rectangular faces.
This setup helps in visualizing the layout of the cuboid and provides a clear reference for solving the angles in question. Applying vector methods involves using the coordinates of points or applying vector rules for angle determination.

Note: When working on such problems, you may use vectors' properties including dot products, unit vectors, and basic trigonometric identities to find angles in a 3-dimensional structure.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fdff7b543-7c53-4567-b2e2-82ba64a4a215%2Fe8d831e3-aaaf-499b-8daf-616c2cd2d771%2Fyfhkz2h.png&w=3840&q=75)
