Homework Help Overview
The discussion revolves around finding the magnitude of the last two cross products involving vectors in a geometric context. The original poster describes a scenario with three vectors forming a triangle, with specific magnitudes and orientations.
Discussion Character
- Exploratory, Assumption checking, Problem interpretation
Approaches and Questions Raised
- Participants explore the relationship between the vectors and the angles involved in the cross products. Questions are raised about the necessary angles for the cross product calculation and the interpretation of the triangle formed by the vectors.
Discussion Status
Some participants are seeking clarification on the original poster's understanding of the angles needed for the cross product. There is a focus on guiding the original poster to articulate their attempts and reasoning without providing direct solutions.
Contextual Notes
The original poster has provided specific details about the vectors' magnitudes and orientations, but there is a noted confusion regarding the triangle's properties, particularly the classification of the triangle formed by the vectors.

Hello, Jr, 
Please don't delete parts of the template. You need them, see guidelines
In your case number 2 in particular. What do you know of the angle you need ? And what do you need for the cross product ?

I have given all information that was provided. Vector A has a magniude of 8 along the positive x axis, Vector B starts at the end of vector A running parallel to the y-axis and a magnitude of 6, Vector C connects the head of Vector B to the tail of Vector A. basically a 45-45-90 right triangle is created by the vectors.

I know you have. But I can't see what you have done so far and why you think you are stuck now. So please show which relevant equation you are trying to apply and show your attempt at solution. I want to help you find the right next step yourself -- the answer is after all not important; it's your ability to do the exercise yourself that we want to achieve ...
And the 3 4 5 Pythagorean triangle is definitely not a 45 45 90 !
