Question 1210528: ABCDEF is a concave hexagon with exactly one interior angle greater than 180 degrees. (The diagram below is not drawn to scale.) Noah measured the marked angles, getting 90, 120, 45, 75, 150, 180, 15, 60, 30. What interior angle measure of the hexagon, in degrees, is missing from Noah's list?

The missing is the mentioned interior angle, which is greater than 180 degrees.

May be, other interior angles are missed, too - the given information does not
allow to judge about it, but the question does not ask about it.

What we can say for sure is that the mentioned angle, greater than 180 degrees,
is not among the presented angles.

Judging the problem in whole, I would say that it is from that kind of problems,
which badly prepared low level substitute teacher may assign in the class,
when he (or she) does not know how to use the class time more productively.

God save us from such teachers . . .
