4. Assume a path is drawn from the fire tower to
Bald Mountain. What is the angle the new path
forms with the old path from Bald Mountain to
the ranger station?

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
