That is inncorrect a pentagon has 5 verticies, that means a pentagon has 5 angles, a shape with 6 angles would be a hexagon.

btw, I figured out the answer.

I use Aops too.

Is this a Math Masters problem?

Do the Alegebera, 

1. 3x=2x+12, we need to bring x terms to 1 side and numberes on the other, we now have 3x-2x=12, 
2. now you need to subtract 3x-2x=x, you now have x=12, 12 is the only value that satifies this equation.

Oh, ok, thanks for the help.

It says that's wrong.

I hope this helps.
