48.8 megabytes. When the download is 17.5% complete, have been downloaded 48.8 megabytes.
The key to solve this problem is using the rule of three.
If 279Mb -------------> 100%
x <------------- 17.5%
x = [(279 megabytes)(17.5)]/100
x = 48.825 megabytes
Round to the nearest tenth 48.8 megabytes.
The length of side bc is 28
(-4, 3, 10). I'm not really sure tho
