Janelle ate 4/5 of her graham cracker. paul ate 3/5 of his graham cracker. the graham crackers were the same size. how much less of his graham cracker did paul eat than janelle ate?

Yes i could be the length of the triangle

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
