\(\displaystyle One \ way:\)
\(\displaystyle We \ have \ three \ triangles \ enclosed \ in \ the \ polygon;\)
\(\displaystyle hence, \ (3)(180^0)-480^0 \ = \ 60^0\)

Thanks.
Interior angle of a polygon = (n - 2) x 180° or (n - 2) x ? radians , where n = number of sides
This particular question was actually directed toward year 9 students in what was a generic numeracy test, which makes me wonder whether they'd be expected to know specically about this formula for the interior angle of a polygon or whether they could roughly estimate the angle in some other fashion.

\(\displaystyle On \ this \ one, \ I \ guess \ that \ it \ depends \ on \ the \ perspicacity \ of \ the \ student.\)
