Helium is considered a noble gas because it has a valence electron shell

Helium has a full valency electron shell

Explanation:

Noble gases are gases at in general they don't react with any other element easily. They are a group of elements that make up Group 18 on the periodic table. They are referred to as inert gases because of their unreactive nature because they have a full valency electron shell. They have the following general properties: colourless, odourless, tasteless, and are nonflammable gases.

I think its like this:

All your really doing is looking at components. And using trig.

1) y=3.3sin(38)(3.6) =7.308m

2) x=3.3cos(38)(3.6)= 9.36m

This should make sense since with a 38 degree slope you will travel more in the horizontal direction than the vertical direction.
