Question 633567
.
Please help me solve, a=?, b=35, c= 37
~~~~~~~~~~~~~~~~~~~~~~~~~



I consider it as a Pythagorean equation


a^2 + b^2 = c^2,


a^2 + 35^2 = 37^2,


a^2 = 37^2 - 35^2 = (37-35)*(37+35) = 2*72 = 144,


a^2 = 144,


a = {{{sqrt(144)}}} = 12.

Looking at Edwin's post, I clearly see that Edwin wants to show his presence here,
but I don't see much point in his introducing a negative value for the quantity 
representing the length of a segment.


Only so I could refute it.
