I know that a2+b2=c2. I also that c is the hypotenuse of a right triangle and a and b are the legs of a right triangle. I know how to work backwards (for example finding b from just the values of c and a, or just the value of c). However, I am still trying to figure out how to find what b is. I keep getting the wrong answer, and suspect it is a simple arithmetic error. But, here is what the problem is:
a= 110
c= 140
Edit: So, here is what I have:
11022+b2=14022
12100+b2=19600
-12100 -12100
__ _____
b2=7500
__
b=25003
Edit: I have checked with 10 other people (7 in my class, 3 in my family) and all of them got that answer. Everyone but my teacher, who marked it wrong. I'm pretty sure everyone else got that as well.
Thank you for your help.
