This graph shows the solution to the inequalities y> 3/2x-2 and y< 3/2x-10. does the system of inequalities have solutions? if so, which region contains the solution? a) there is no solution b) there is a solution, and it’s shown by region a. c) there is a solution, and it’s shown by region c d) there is a solution, and it’s shown by region b.

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?
