help please!! easy for some not for all What is the sum of the measures of the interior angles of a regular polygon where a single exterior angle measures 72°?

OpenStudy (mertsj):

What is the sum of ALL of the exterior angles of a regular polygon?

OpenStudy (anonymous):

360 right

OpenStudy (mertsj):

So if one exterior angle is 72, how many exterior angles are there?

OpenStudy (anonymous):

5

OpenStudy (mertsj):

So how many sides does the polygon have if there are 5 exterior angles?

OpenStudy (anonymous):

5

OpenStudy (mertsj):

So it must be a pentagon.

OpenStudy (mertsj):

Into how many triangles can a pentagon be divided?

OpenStudy (mertsj):

|dw:1334364488386:dw|

OpenStudy (anonymous):

three

OpenStudy (mertsj):

How many degrees in each triangle?

OpenStudy (anonymous):

180

OpenStudy (mertsj):

How many degrees in all three triangles?

OpenStudy (anonymous):

540

OpenStudy (mertsj):

How many degrees in the interior angles of the regular polygon which has exterior angle or 72 degrees?

OpenStudy (anonymous):

108

OpenStudy (anonymous):

i think

OpenStudy (mertsj):

Reread the question your problem asks.

OpenStudy (anonymous):

so is the answer 108 or 540 haha

OpenStudy (mertsj):

What does the problem ask? Does it ask for one interior angle or all interior angles?

OpenStudy (anonymous):

all of them so it would 540 right

OpenStudy (mertsj):

Way to go. You are very smart.

OpenStudy (anonymous):

ha right thanks for the help
