Tyler has two savings accounts that his grandparents opened for him. One of the accounts pay 8% annual
interest, whereas the other pays 9 % annual interest. If you have $800 more invested at 9% than you invest
at 8 % , how much do you have invested in each account if the total amount of interest you earn in a year is $140?

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?
