Question 1012347

135° is the measure of the
interior angle, what is the value of "n" in n-gon?
<pre>This appears to be a REGULAR n-gon.
Since one of its interior angles is {{{135^o}}}, it follows that one of its exterior angles = {{{45^o}}} ({{{180^o -135^o}}})
With an exterior angle being {{{45^o}}}, number of sides, or n = {{{360/45}}}, or {{{highlight_green(8)}}}. 
FYI: This is an OCTAGON.
