Question 1210523
.
The interior angles of a polygon form an arithmetic sequence. The difference between the largest angle 
and smallest angle is $148^\circ$. If the polygon has 3 sides, then find the smallest angle, in degrees.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~



As I read the problem, I see that it is about a triangle, whose interior angles form
an arithmetic sequence.


Then I immediately conclude that the central angle of this AP is 60 degrees
(since the sum of the three angles is 180 degrees).


I also conclude that the doubled common difference of the AP is 148 degrees, so 
the common difference itself is 148/2 = 74 degrees.


Having it, I immediately conclude that the problem is erroneous: it is self contradictory
and describes a situation which NEVER may happen: it produces the interior angle of this triangle 
which has the negative measure of 60-74 = -14 degrees.


Taking everything into account, I conclude that the problem in whole is heavily defective and terminally ill.
