Answer 1

Students are less likely to get help when the name changes with questions of the same type, posted so close together. Please do not use name changes to get more of your questions answered. It doesn't work with me

Answer 2

I'm sorry I don't understand what you mean. I didn't do any name changes. You might be confusing me with someone else.

Answer 3

Just plug in the numbers likewise:

N= mg/ cos (theda)

That will give you your answer!
