Renee pays for a cat toy with a $10 bill and receives $4.35 in
change. The equation 10 – c = 4.35 gives the cost in dollars of
the cat toy. Determine whether c=5.35, c = 5.65, or c = 6.35
is a solution of the equation, and tell what the solution means.

Here is their argument. given the obtuse angle x, we make a quadrilateral abcd with ∠dab = x, and ∠abc = 90◦, and ad = bc. say the perpendicular bisector to dc meets the perpendicular bisector to ab at p. then pa = pb and pc = pd. so the triangles pad and pbc have equal sides and are congruent. thus ∠pad = ∠pbc. but pab is isosceles, hence ∠pab = ∠pba. subtracting, gives x = ∠pad−∠pab = ∠pbc −∠pba = 90◦. this is a preposterous conclusion – just where is the mistake in the "proof" and why does the argument break down there?
