Okay so I have to sleep soon for school and I really need help. I've already tried and couldn't do it so can someone help me. A source of laser light sends Ray's AB and AC toward two opposite walls of a hall. The light rays strike the walls at points B and C. What is the difference between the walls? It's 20m 40m 60° and 45°. Please help
