A regular polygon with an interior angle measuring 156 degrees is called?

ganeshie8 (ganeshie8):

convex, do u have options ?

OpenStudy (colcaps):

what do you mean convex?

OpenStudy (colcaps):

i mean options

ganeshie8 (ganeshie8):

is it multiple choice q ?

OpenStudy (colcaps):

nope

OpenStudy (colcaps):

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?

ganeshie8 (ganeshie8):

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

ganeshie8 (ganeshie8):

its okay :) too many to rememebr huh

OpenStudy (colcaps):

its a pentadecagon

ganeshie8 (ganeshie8):

looks reasonable to me :) go wid it

OpenStudy (colcaps):
