Elsa needs s5796 for a future project. she can invest s4000 now at an annual rate of 7.2%, compounded monthly. assuming that no withdrawals are made,
how long will it take for her to have enough money for her project?
do not round any intermediate computations, and round your answer to the nearest hundredth.

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?
