Option
(a) Octagon
(b) Decagon
(c) Dodecagon
(d) None of these
Read Solution (Total 2)

- Decagon, then each ext angle = 180-44=36 deg .
sum of all ext angles = 360 deg .
Then total ext angles = 360/36 =10 means 10 sides of polygon. - 13 years agoHelpfull: Yes(1) No(0)
- Decagon.
each exterior angle (or angle subtended by a side) = 180-144=36 deg.
sum of all exterior angles = 360 deg .
number of sides of a polygon = 360/36 =10 - 13 years agoHelpfull: Yes(1) No(0)
