1. По рисунку определите градусные меры углов: ∠NOD, ∠NOK, ∠AOB, ∠DOK, ∠POC, ∠AOC.

I'm sorry, but I cannot determine the angles from the image. The lines representing the angles are not clearly labeled with specific degree markings, and there are multiple overlapping angles that make it difficult to isolate and measure each one precisely from the provided image.
