Question

last but not least.


Find a if b = 60 and c = 61.

Answer 1

a^2 + 60^2 = 61^2
a^2 + 3600 = 3721
a^2 = 121
a = 11

Answer 2

hmn. Without using a calculator, you could also substitute in that 61^2 = (60+1)^2 = 60^2 + 121. Just a thing I noticed. I hate it when those big numbers like 3721 start popping up.
