The rafters form a triangle with the base angles 36 and the peak angle 180-72=108
\n" ); document.write( "If we drop a line from the peak angle to the middle of the house that is at 16 feet \r
\n" ); document.write( "\n" ); document.write( "We have a right triangle with one leg 16.
\n" ); document.write( "We have angles 36 90 and 54\r
\n" ); document.write( "\n" ); document.write( "the hypotenuse will be the length of the roof from the peak to the 36 degree angle.
\n" ); document.write( "so we have the base as 16 and the hypotenuse
\n" ); document.write( "we have hypotenuse and adjacent (16) and angle 36
\n" ); document.write( "After you calculate the rising rafter, be sure to add 2 feet. \n" ); document.write( "
