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.
For example, if the strike price for a call option is USD $1 and the price of the underlying is USD 1.20, then the option has an intrinsic value of USD 0.20. The value of an option is the sum of its intrinsic and its time value. Equity
