solve
ganeshie8 (ganeshie8):
ok good :)
ganeshie8 (ganeshie8):
we use the same formula
ganeshie8 (ganeshie8):
we need to find how many sides this polygon will have, then we can name it
OpenStudy (colcaps):
so 360-156?

thats doesnt give useful info
OpenStudy (colcaps):
or 180-156?
ganeshie8 (ganeshie8):
right !
OpenStudy (colcaps):
i got 24
ganeshie8 (ganeshie8):
since 156 is the interior angle,
180-156 is its exterior angle

ganeshie8 (ganeshie8):
so, exterior angle = 24, ha ?
OpenStudy (colcaps):
yeash
ganeshie8 (ganeshie8):
we use the same formula we have been using forever like
OpenStudy (colcaps):
so thats the answer or we will divide it by 2?
ganeshie8 (ganeshie8):
exterior angles sum to 360,
so,
24x = 360
x = 360/24
= ?

OpenStudy (colcaps):
oh right the answer is 15
ganeshie8 (ganeshie8):
that gives the number of angles, which is same as number of SIDES
OpenStudy (colcaps):
i always forget the formula
ganeshie8 (ganeshie8):
so what a polygon wid 15 sides called ?
OpenStudy (colcaps):
uhhmm wait
