I've always enjoyed Algebra/Calculus. I wish I could say the same about problems. Lately, I've been trying to improve my work problem solving skills, but I always find myself in need of someone's help, and that's why I'm here. I need help with this even problem. I don't know where or how to start. All I could think about was the Pythagorean theorem but that was about it. Some one please show me how to do this problem since there are more of it that I'm willing to try, but unless I havbe an example than I can get ideas from, I feel like I'm going nowhere. Your help will be most appreciated.
