<PRE><B>Question 423918</B>
Int = Ext + 3*Ext = 4*Ext
4Ext + Ext = 180
Ext angle = 36 degs
-----------------
The exterior angle = 36 degs
The sum of ext angles of all polygons = 360 degs
360/36 = 10 sides
----------------
----------------
PS  3 times larger is not the same as 3 times as large.
3 times larger = 4 times as large
300% more is 400% of the base, or 4 times as much
