Looking at the figure makes me dizzy..

How on Earth do you do this problem??

It's all about calcuating hypoteneese.

i've seen it but never bothered to give it a try, computation isn't my thing

God I'm having trouble just keeping track of everything

piece of cake

 

[DeadWolfe]

The answer is clearly c).

No, it's "none of the above".

That means you need to brush up on organizing information!

I'm confused, the first thing it says is that ABCD is a square prism...it sure as heck doesn't look like one to me... as for the other stuff, it's just simple geometric calculations isn't it? I think all you need to know are the rules governing angles and shapes.

 

[PowerIso]

That's correct, but until you actual start working on the problem, it's rather tedious.

The problem can be solved by taking it as a vector problem. Assign a vector for every two coordinates of relevance and try to derive the results.
