Find the length of side a in the right triangle. If b = 12 and c = 15.
\n" ); document.write( "I used the equation a^2 + b^2 = c^2
\n" ); document.write( "So far the answer that I came up with was a=√81 but I'm not sure if this is right and I think I have to simplify.
\n" ); document.write( "--------------
\n" ); document.write( "sqrt(81) is correct.
\n" ); document.write( "That's 9.
