Connect segment PO, and name the interaction of PO and the circle as point M. Since PB and PD are tangent to the circle, it's easy to see that M is the midpoint of arc BD. ∠ BOA = 1/2 arc AB + 1/2 arc CE. Since AC // DE, arc AD = arc CE, thus, ∠ BOA = 1/2 arc AB + 1/2 arc AD = 1/2 arc BD = arc BM = ∠ BOM.

Many students across the country were shocked when they saw the cutoff scores for the USAJMO- a prestigious math olympiad- this year, because they were more than 10 points higher than what they had been in previous years and for tests of similar difficulty. Even more surprising was the fact that only 158 students qualified for the exam, when there are usually around 250 every year.
