Each angle is 108 degrees. Times that by five and they ye go. 540

What do you think the answer is?
OpenStudy (peterg2001):
not 540 for sure i tried that
OpenStudy (anonymous):
To add to what @Mech123 said, he came to that 108 degrees by knowing that the exterior angles all add up to 360, so we know each angle is 360/5=72. Then the interior angle is 180-72=108. There's 5 of them so 5*108=540.
