Best ResponseYou've already chosen the best response.0im assuming a,b,and c are degrees. then b+c=90

Best ResponseYou've already chosen the best response.0Yes, the pythagorean theorem... and to tell the truth i have absolutely no idea what that means

Best ResponseYou've already chosen the best response.0just plug in everything you know into the pythagorean theorem. then rearrange what you get so that you can use the quadratic formula.

Best ResponseYou've already chosen the best response.0(3y10)^2  (y+40)^2 = 90^2

Best ResponseYou've already chosen the best response.0well.... i did the same thing except i used a squared plus b squared equals c squared

Best ResponseYou've already chosen the best response.0i tried this: a=90,b=y+40,c=3y10 a2+b2=c2 squared=2 so 902+(y+40)2=(3y10)2 8100+y2+1600=3y2+100 9700+y2=3y2+100 9600+y2=3y2=2y2+100 9600=2y2 4800=y2

Best ResponseYou've already chosen the best response.0you squared incorrectly. (y+40)^2 is y^2+80y+1600. same with (3y10)^2, that was squared incorrectly too

Best ResponseYou've already chosen the best response.0hmmm. write out (y+40)x(y+40). then distribute. so it becomes y*y + y*40 + 40*y + 40*40

Best ResponseYou've already chosen the best response.0lol no problem. by the way, the answer isn't a whole number.

Best ResponseYou've already chosen the best response.0I'm in seventh grade honors and lets just say my teacher isnt exactly very to the point. and oh are you serious? so its not a perfect square?

Best ResponseYou've already chosen the best response.0ohhh jeez. i was having a hard time the whole time because i thought it HAD to be a perfect square... :) whoops.
