Mark Gonzalez makes his first submission to Road Sign Math with a splash. Mark is a fan of mathematics, and has been looking for a while for a sign to submit. He certainly did a great job with this one. Mr. Gonzalez did however leak this sign on his own blog before it's release here. Tsk tsk.

Applause for Mr. Gonzalez's creative use of trigonometry and avoiding any penalty by using cancelling math.

$\tan (78 + 78 + 69)^\circ + 4 = 5$

This sign is found in Jasper, Alabama while traveling eastbound on highway 78.
