A tennis court measures 78 feet long and 27 feet wide. To the nearest foot, what is the length of the diagonal of the court? Show all your work please.
What about the LaTex. Where did that come from? Although I suppose only one line of it is specifically in Latex.
Yes GeoGebra is the program that I use for these sorts of pics. It is a free download and it can do a lot of things. It is not intuitive when you first start but you'll get the hang of it pretty soon. You can use LaTex with it too. I still learn new things with it all the time.
You should download it and have a play.
