Hey guys I am brand new here. I am a 15 year old currently in 10th grade of high school. I am in geometry but some parts are just really hard about it. I cannot afford a tutor, and the way my teacher explains things is just really confusing. She just gave us a large worksheet with problems that I need some help with. I am not giving all the numbers because the ones i left out, i have already completed. If you could just put your answer next to a number that would be awesome. Thanks so much for all your help
