Finding Unknown Angles using Diagrams

A store owner faces a challenge with security camera coverage. The lesson teaches how to find unknown angles in real-world scenarios by decomposing and recomposing angles. The store's camera setup is analyzed, and calculations are made to determine the missing angle coverage. The owner must choose the right lens size to ensure full coverage. The video concludes with a summary of the angle concepts learned.
