2. For the house roof and dormer roof, Pitch-Perfect decides
to use a king-post truss configuration as shown in the figure.
Because the porch roof slopes in only one direction, its truss
will be in the shape of a right triangle with only one rafter,
one strut, and one-half of a tie beam. (Think of it as the right
half of the figure shown.). Using the pitch angles from Step 1,
Tie Beam
David must now calculate (a) the rise of the roof (the king-
post length), (b) the rafter length, and (c) the strut length for each of the three sections of the roof. Calculate
these three lengths for each section and write your answers in feet and inches to the nearest inch.
