A cottage under construction is to be 12.6 meters wide. The two sides of the roof are to be supported by rafters that meet at a 50 degree angle.How long should the rafters be?
sin 25 = 6.3/L
solve for L
However, being mathematicians and not carpenters, we left no overhang beyond the walls and the water will run down the walls and peel the paint and flood the basement :)
