OpenStudy (anonymous):

wait how do you find that

OpenStudy (anonymous):

no, the side length

OpenStudy (anonymous):

how do you know it's 5

OpenStudy (bee_see):

5 is half of 10

OpenStudy (anonymous):

the side length

OpenStudy (anonymous):

but....wait why would the side be half of the apothem?

OpenStudy (bee_see):

Since the apothem is 10, the side length is 10.

OpenStudy (anonymous):

it's not a equiangular triangle

OpenStudy (anonymous):

that's a hexagon

OpenStudy (anonymous):

hexagons have equiangular triangles when divided by radii

OpenStudy (bee_see):

you wrote pentagon

OpenStudy (anonymous):

pentagons don't have equiangular triangles when divided by radii.

OpenStudy (anonymous):

it is a pentagon.
