Please know that I am not looking for somebody to give me the answers to these questions! If you can explain how to solve these problems, please do. I'm really struggling in Geometry, so any help that you can give is much welcome! :) I will be awarding brainliest answer to the person who is clearest and helps me to better understand this! Thank you so much in advance! :)
