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.
A call option is âin the moneyâ when the strike price is below the market price of the underlying stock. For a put option, itâs the opposite; a put is âin the moneyâ when the strike price is above the market price of the underlying stock. For example, if you buy Google January 620 call options now and two weeks later Google is trading for $623.00, then you are in the money by $3.00.
