SUMMARY
The discussion focuses on solving a problem involving the cross product of vectors to find the magnitude of the last two products. Vector A has a magnitude of 8 along the positive x-axis, while Vector B has a magnitude of 6 and runs parallel to the y-axis. The vectors create a right triangle, specifically a 45-45-90 triangle, which is incorrectly referenced as a 3-4-5 triangle. The key to solving the problem lies in understanding the angle required for the cross product and applying the relevant equations correctly.

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 !
