Find the measure of each exterior angle of a regular hexagon.

OpenStudy (anonymous):

There are two angles formed wherever two sides of the hexagon meet. The angle inside the hexagon is 120 degrees and the angle outside the hexagon is 360 - 120 = 240 degrees (:

The exterior angle is supplementary with the interior angle (supplementary meaning x + y = 180). At least, that's how I learned it. http://answers.yahoo.com/question/index?qid=20080124181200AAbLbpQ I used to think Noemi's way, but that is what I learned in Math class.

OpenStudy (anonymous):

\[180 - \frac{ \left( sides - 2 \right) \times 180 }{ sides } = answer\]

OpenStudy (anonymous):

\[180 - (5-2) x 180 ???\]

OpenStudy (anonymous):

\[180 - \frac{ \left( 6 - 2 \right) \times 180 }{ 6 } = answer\]

OpenStudy (anonymous):

so my answer is 90 ????

OpenStudy (anonymous):

You messed up somewhere in your math. Start with the (6 - 2) * 180 part and tell me the answer you get.

OpenStudy (anonymous):

6-2 = 4 x 180 = 720

OpenStudy (anonymous):

Good, now divide it by the number of sides.

OpenStudy (anonymous):

120

OpenStudy (anonymous):

Now finish the equation (now that you have solved the fraction part).

OpenStudy (anonymous):

i got 60 .......

OpenStudy (anonymous):

That's your answer. :)

thank you so much appreciate it
