If the hypotenuse of a right triangle is 20, and one of the legs is 15,
\n" ); document.write( " what is the missing side?
\n" ); document.write( ":
\n" ); document.write( "a^2 + b^2 = c^2,
\n" ); document.write( "a^2 + 15^2 = 20^2
\n" ); document.write( "a^2 + 225 + 400
\n" ); document.write( "a^2 = 400 - 225
\n" ); document.write( "a^2 = 175
\n" ); document.write( "a = \"sqrt%28175%29\"
\n" ); document.write( "a ~ 13.23
\n" ); document.write( "
