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.
