hmm really. why don't you post them if you can't solve one out of three anyways? Did you read my post? Question 2 & 3 should be solved similarly (assigning a coordinate system, finding plane normals and using dot product) if you used this method 3 is solved exactly like 2 but less work because you are already given two vectors. Or maybe I am overthinking the problem...i'm pretty sure we learned vectors and dot product in highschool... if noone posts answers to this by next monday, i'll be done my after-finals partying by then and try to solve it.
