OpenStudy (anonymous):

is this asking the area of hex/area triangle?

OpenStudy (mathmath333):

yes

OpenStudy (phi):

You could use 30-60-90 triangles to figure it out.

OpenStudy (mathmath333):

on which triangle ?

OpenStudy (phi):

it's a bit complicated. but the interior angles of the hexagon are 120 degrees the equilateral triangle uses up 60 degrees, so the "other 2" are 30 degree |dw:1427317124662:dw|
