The result for a sum of all interior angles for #N#-sided convex polygon is #N*180^o - 360^o = (N-2)*180^o# In #N#-sided regular polygon all #N# angles are equal, so each is equal to #((N-2)/N)*180^o# For #N=9# this gives a measure of one interior angle of a regular 9-sided polygon: #((9-2)/9)*180^o = 140^o#
The intrinsic, or gross, value of an option is the amount the option is in the money. For example, if you have the option to pay $10 per share for a stock that trades for $15, the option has an intrinsic value of $5 per share.
