@cutie_pie_1213 everything good now?

OpenStudy (anonymous):

how did u get that jw i dont understand this one at all

OpenStudy (anonymous):

the sum of exterior angles is 360

OpenStudy (anonymous):

divide 72 by 360, thats 5

OpenStudy (anonymous):

that means 5 angles, so once you find the measure of one interior angle, you multiply that by 5

OpenStudy (anonymous):

to find the measure of one interori angle, subtract 72 from 180, since an exterior angle is an extension of an angle |dw:1337876398035:dw|

OpenStudy (anonymous):

ohh okay

OpenStudy (anonymous):

108 * 5 = 504 <- thats your answer

OpenStudy (anonymous):

everything good?

OpenStudy (anonymous):

yes thank u
