a right Triangle has perimeter of 36cm.
\n" ); document.write( "a + b + c = 36
\n" ); document.write( " one leg is 9cm determine the length of other leg and hypotenuse.
\n" ); document.write( "9 + b + c = 36
\n" ); document.write( "b + c = 36 - 9
\n" ); document.write( "b + c = 27
\n" ); document.write( "b = (27-c)
\n" ); document.write( ":
\n" ); document.write( "a^2 + b^2 = c^2
\n" ); document.write( "replace b with (27-c)
\n" ); document.write( "9^2 + (27-c)^2 = c^2
\n" ); document.write( "81 + 729 - 54c + c^2 = c^2
\n" ); document.write( "810 - 54c = c^2 - c^2
\n" ); document.write( "810 = 54c
\n" ); document.write( "c = 810/54
\n" ); document.write( "c = 15
\n" ); document.write( "then
\n" ); document.write( "b = 27 - 15
\n" ); document.write( "b = 12
\n" ); document.write( "Hypotenuse = 15, one side = 12
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check
\n" ); document.write( "9^2 + 12^2 = 15^2
\n" ); document.write( "81 + 144 = 225\r
