Read the problem and examine the diagram. 14 students in neil's class play basketball.35 % of the students in his class play basketball. how many total students are in neil's class? which choice is not a correct way to check your answer? a.35% of the answer should be 14. b. the answer times 35% should be 14. c. the answer should be 35% of 14. d.14 should be 35% of the answer.

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?
