i dont have adobe on this computer, is this the problem with the sum of the sine of the angles?

If it is then, i remember using complementary angles. For example sin 3+sin87=1, the same goes for angles like sin93+sin177=1. All of these complementary angles add up to 1 and there are 30 pairs of these angles so the answer is 30. You can also set up a summation equation using the same logic.

Hope this helps.
