90 degrees is a right angle. So greater is obtuse, less is acute.

Try to remember it like this: Obese=Obtuse----Little=Cute so Acute.

|x|+2=4 i need help wit math home work pre algebra?

We Answered:

what are you trying to get by itself?
"X" so to get x by itself you need to subtract 2 from both sides
|x|+2=4
-2 = -2

Now your left with |x|=2
those little lines just mean "absolut value" that just means anything that is inside will have a final answer that is a positive number. And since x already is a positive number you don't need to worry about them.
So x=2
Open your math book and look at examples if your having trouble.
