Question 81537: I am doing apythagorean theorem problem, here the problem
a squared + b squared + c squared
a= 8 b=15 c=?
8 squared + 15 squared = c squared
64 + 225 = c squared
c squared = 64 + 225
c squared = 289
c = 17
my question is how can you subract the squared from 289 to 17 without the calculator, I know I cannot divded by 2 since it came out 144.5 . Is there a way for me to figured this out?
