**
The first part of the problem was easy enough as was finding the directions of the other two, but I am having trouble finding the correct angle for the last two cross products in order to find the magnitude.**

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 ?

And the 3 4 5 Pythagorean triangle is definitely not a 45 45 90 !
