Math On The Serengeti

This is only the second time that Road Sign Math has left the borders of the United States, this time going to the far reaches of civilization in Tanzania. Road Sign Math veteran Pam Coffield (see Shiloh) found this sign in her collection of photos from her safari. While it was taken before she was technically playing the game, it works wonderfully. Pam dedicated this sign to Mazie, the daughter of the founder of Road Sign Math with the wish that she "take Road Sign Math to all regions of the world."



This sign brings six numbers to the party. You may think that at some point if you have enough numbers there will always be some relationship, however I can tell you from many submissions that is definitely not the case. The math here is not easy to find.

$$152 - ( 319 - 199 ) = 32 \bmod ( 64 + 28 )$$

This sign is found in Tanzania, but we are not exactly sure where. I inquired with the submitter if she might have GPS coordinates and she definitely does not. If you wish to find this sign for yourself, you will have to hunt it down. After doing some digging we were able to find the approximate location of this sign.

Ed.: It was pointed out after posting by David Slauenwhite, who is on a trigonometry "jag" as of late, that there is a very elegant trigonemetry solution for this sign.

$${ {\cos (152 + 28)^\circ} \over { \cos (319 - 199)^\circ} } = { 64 \over 32 } \rightarrow { \cos 180^\circ \over \cos 120^\circ } = 2 \rightarrow { -1 \over {- {1 \over 2} } } = 2 \rightarrow 2 = 2$$
