HeLP please Given the regular polygon, find the measure of each numbered angle.

OpenStudy (anonymous):

OpenStudy (ac3):

there are 1080 degrees in an octagon

OpenStudy (anonymous):

ok

OpenStudy (ac3):

it's split up into 8 triangles. And one triangle has 180 degrees. this part is not super necessary but may help us.

OpenStudy (ac3):

so from what it looks like angle 2 must me the same as the angle right under it correct?

OpenStudy (anonymous):

yes

OpenStudy (ac3):

brb

OpenStudy (anonymous):

alright

OpenStudy (ac3):

It may even be the same as angle 1 that looks like an equilateral triangle all angles in an equilateral triangle are exactly the same

OpenStudy (ac3):

therefore i'm gonna say the answer is c because if they are all 60 the will indeed add up to 180

OpenStudy (anonymous):

okay can you help me with one more?

OpenStudy (ac3):

now we can verify this by process of elimination

OpenStudy (ac3):

oh was that right?

OpenStudy (anonymous):

OpenStudy (ac3):

you probably will want to open up another question stream thing

OpenStudy (anonymous):

okay hold on
