A carpenter needs to cut six 16-inch-long pieces of wood. How many feet of wood does the carpenter need? A. 192 ft B. 8 ft C. 1 1/3ft D. 32 ft

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct
