Answer: 11 because the distance between A-B is 8 so because it says it on top, then add 3 to it from B to C
31.62
You use pythagorean theorem so 30 is legA and 10 is legB so 20^2+10^2= square root legC which is 31.62
C=3 that’s the answer I think
Domain are the values of x, range are the values of y
